Round long double value to long long int. * sysdeps/libm-i387/s_rinttoll.S: New file. * sysdeps/libm-ieee754/s_rintl.c: Many corrections. The previous version was full of errors. * math/math.h (rinttol): Argument is of type `long double' not `double'. (rinttoll): Likewise. (roundtol): Likewise. (roundtoll): Likewise. 1997-04-06 11:32 H.J. Lu <hjl@gnu.ai.mit.edu> * posix/getopt.c (_getopt_initialize): Preserve optind. (_getopt_internal): Set optind to 1 if optind == 0 before calling _getopt_initialize (). 1997-04-05 16:45 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/rpcsvc/nislib.h: Change const nis_name to new type const_nis_name. * nis/nis_intern.c: Likewise. * nis/nis_intern.h: Likewise. * nis/nis_server.c: Likewise. * nis/nis_subr.c: Likewise. * nis/nis_table.c: Likewise. * nis/nis_names.c: Likewise.

# A problem with this script is that we must be able to handle symbolic
|
|
# links somewhere in the paths of either path. To resolve symlinks we use
|
|
# the `pwd' program. But some `pwd' programs are no real programs but
|
|
# instead aliases (defined by the user) or builtins (as in bash-2). Both
|
|
# kinds have in common that they might not give the correct result. E.g.,
|
|
# the builtin in bash-2 returns the path which was used to change to the
|
|
# directory and not the real path.
|
|
#
|
|
# To prevent this problem we make sure the real `pwd' somewhere in the
|
|
# path is used. Currently there is only support for bash-2 available.
|
|
# If other shells also have problems we have to add more code here.
