A few 'long double'-related tests include math_private.h just for their variety of math_ldbl.h, which contains macros for assembling and disassembling the binary representation of 'long double'. math_ldbl.h insists on being included from math_private.h, but if we relax this restriction (and fix some portability sloppiness) we can use it directly and not have to expose all of math_private.h to the testsuite. * sysdeps/generic/math_private.h: Use __BIG_ENDIAN and __LITTLE_ENDIAN, not BIG_ENDIAN and LITTLE_ENDIAN. * sysdeps/generic/math_ldbl.h * sysdeps/ia64/fpu/math_ldbl.h * sysdeps/ieee754/ldbl-128/math_ldbl.h * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h * sysdeps/ieee754/ldbl-96/math_ldbl.h * sysdeps/powerpc/fpu/math_ldbl.h * sysdeps/x86_64/fpu/math_ldbl.h: Allow direct inclusion. Use uintNN_t instead of u_intNN_t. Use __BIG_ENDIAN and __LITTLE_ENDIAN, not BIG_ENDIAN and LITTLE_ENDIAN. Include endian.h and/or stdint.h if necessary. Add copyright notices. * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h (ldbl_canonicalize_int): Don't use EXTRACT_WORDS64. * sysdeps/ieee754/ldbl-96/test-canonical-ldbl-96.c * sysdeps/ieee754/ldbl-96/test-totalorderl-ldbl-96.c * sysdeps/ieee754/ldbl-128ibm/test-canonical-ldbl-128ibm.c * sysdeps/ieee754/ldbl-128ibm/test-totalorderl-ldbl-128ibm.c: Include math_ldbl.h, not math_private.h.
