Proposed by Joe Keane . 1997-11-04 23:57 Ulrich Drepper * configure.in: Correct gcc -pipe test. Patch by Zack Weinberg . * posix/glob.c: Cleanups. Patch by H.J. Lu . 1997-11-04 Andreas Jaeger * manual/creature.texi (Feature Test Macros): Add _POSIX_C_SOURCE definition. --- sysdeps/posix/getcwd.c | 192 ++++++++++++++++++++++++++---------------------- sysdeps/posix/ttyname.c | 7 +- sysdeps/posix/writev.c | 5 +- 3 files changed, 108 insertions(+), 96 deletions(-) (limited to 'sysdeps/posix') diff --git a/sysdeps/posix/getcwd.c b/sysdeps/posix/getcwd.c index 865bd3fa6a..01f86ef47f 100644 --- a/sysdeps/posix/getcwd.c +++ b/sysdeps/posix/getcwd.c @@ -26,12 +26,12 @@ */ /* AIX requires this to be the first thing in the file. */ -#if defined (_AIX) && !defined (__GNUC__) +#if defined _AIX && !defined __GNUC__ #pragma alloca #endif #ifdef HAVE_CONFIG_H -#include "config.h" +# include "config.h" #endif #include @@ -39,92 +39,91 @@ #include #ifdef STDC_HEADERS -#include +# include #endif -#if !defined(__GNU_LIBRARY__) && !defined(STDC_HEADERS) +#if !defined __GNU_LIBRARY__ && !defined STDC_HEADERS extern int errno;
