Remove __need macros from errno.h (__need_Emath, __need_error_t). This is fairly complicated, not because the users of __need_Emath and __need_error_t have complicated requirements, but because the core changes had a lot of fallout. __need_error_t exists for gnulib compatibility in argz.h and argp.h. error_t itself is a Hurdism, an enum containing all the E-constants, so you can do 'p (error_t) errno' in gdb and get a symbolic value. argz.h and argp.h use it for function return values, and they want to fall back to 'int' when that's not available. There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic. Reorganize file. Declare errno here. When __ASSEMBLER__ is defined, don't declare anything other than the E-constants. * include/errno.h: Change conditional for exposing internal declarations to (not _ISOMAC and not __ASSEMBLER__). * bits/errno.h: Remove logic for __need_Emath.

Remove __need macros from errno.h (__need_Emath, __need_error_t). This is fairly complicated, not because the users of __need_Emath and __need_error_t have complicated requirements, but because the core changes had a lot of fallout. __need_error_t exists for gnulib compatibility in argz.h and argp.h. error_t itself is a Hurdism, an enum containing all the E-constants, so you can do 'p (error_t) errno' in gdb and get a symbolic value. argz.h and argp.h use it for function return values, and they want to fall back to 'int' when that's not available. There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic. Reorganize file. Declare errno here. When __ASSEMBLER__ is defined, don't declare anything other than the E-constants. * include/errno.h: Change conditional for exposing internal declarations to (not _ISOMAC and not __ASSEMBLER__). * bits/errno.h: Remove logic for __need_Emath.

Remove __need macros from errno.h (__need_Emath, __need_error_t). This is fairly complicated, not because the users of __need_Emath and __need_error_t have complicated requirements, but because the core changes had a lot of fallout. __need_error_t exists for gnulib compatibility in argz.h and argp.h. error_t itself is a Hurdism, an enum containing all the E-constants, so you can do 'p (error_t) errno' in gdb and get a symbolic value. argz.h and argp.h use it for function return values, and they want to fall back to 'int' when that's not available. There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic.

Remove __need macros from errno.h (__need_Emath, __need_error_t). This is fairly complicated, not because the users of __need_Emath and __need_error_t have complicated requirements, but because the core changes had a lot of fallout. __need_error_t exists for gnulib compatibility in argz.h and argp.h. error_t itself is a Hurdism, an enum containing all the E-constants, so you can do 'p (error_t) errno' in gdb and get a symbolic value. argz.h and argp.h use it for function return values, and they want to fall back to 'int' when that's not available. There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic.
