From a1aa1d3077cf008c27eb9411fd247f695dbf6bbc Mon Sep 17 00:00:00 2001 From: jb Date: Wed, 9 Nov 2011 18:25:58 +0000 Subject: Configure cleanup. 2011-11-09 Janne Blomqvist * configure.ac (AC_STDC_HEADERS): Remove. (AC_HEADER_TIME): Remove. (AC_HAVE_HEADERS, AC_CHECK_HEADERS): Move into a single invocation of AC_CHECK_HEADERS_ONCE, don't check for presence of C89 headers. (AC_CHECK_MEMBERS): Use single invocation. (AC_CHECK_FUNCS): Move into single invocation of AC_CHEC_FUNCS_ONCE, don't check for presence of C89 functions. * config.h.in: Regenerate. * configure: Regenerate. * intrinsics/clock.c: Include time.h. (mclock): Assume clock() is present. (mclock8): Likewise. * intrinsics/ctime.c (strctime): Assume strftime is present. (fdate): Assume time() is present. (fdate_sub): Likewise. (ctime): Likewise. * intrinsics/date_and_time.c: Don't provide abs macro. (HAVE_NO_DATE_TIME): Remove code related to macro which is never set. * intrinsics/execute_command_line.c: Assume stdlib.h is present. * intrinsics/exit.c: Likewise. * intrinsics/extends_type_of.c: Likewise. * intrinsics/gerror.c: Assume strerror() is present. * intrinsics/kill.c: Assume signal.h is present. * intrinsics/malloc.c: Assume stdlib.h is present. * intrinsics/move_alloc.c: Likewise. * intrinsics/perror.c: Assume perror() is present. * intrinsics/signal.c: Assume signal.h is present. * intrinsics/stat.c: Assume stdlib.h is present. * intrinsics/system.c: Likewise. * intrinsics/time.c: Include time.h, assume time() is present. * intrinsics/time_1.h: Conditionally include sys/time.h, unconditionally time.h. (gf_cputime): Do division in double, fallback using clock(). (gf_gettime): Assume time() is present. * intrinsics/umask.c: Assume stdlib.h is present. * runtime/backtrace.c: Likewise. * runtime/compile_options.c: Assume signal.h is present, assume C89 signals are present. * runtime/error.c: Assume signal.h and stdlib.h are present. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@181227 138bc75d-0d04-0410-961f-82ee72b054a4 --- libgfortran/runtime/backtrace.c | 1 + libgfortran/runtime/compile_options.c | 24 ++---------------------- libgfortran/runtime/error.c | 7 ------- 3 files changed, 3 insertions(+), 29 deletions(-) (limited to 'libgfortran/runtime') diff --git a/libgfortran/runtime/backtrace.c b/libgfortran/runtime/backtrace.c index 606dd34e9d4..e28bdcbc423 100644 --- a/libgfortran/runtime/backtrace.c +++ b/libgfortran/runtime/backtrace.c @@ -25,6 +25,7 @@ see the files COPYING3 and COPYING.RUNTIME respectively.
