https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=2d8adcbd07fc12a3212a9f045605ef712f5fb3ab
commit 2d8adcbd07fc12a3212a9f045605ef712f5fb3ab
Author: Markus Metzger <markus.t.metzger@intel.com>
Date: Tue Feb 20 11:48:01 2018 +0100
gnulib: import mkstemp
Older versions of MinGW do not support mkstemp causing:
gdb/unittests/scoped_fd-selftests.c:37:29: error: \
'mkstemp' was not declared in this scope
int fd = mkstemp (filename);
^
gdb/unittests/scoped_fd-selftests.c: In function 'void
selftests::scoped_fd::test_release()':
gdb/unittests/scoped_fd-selftests.c:56:29: error: \
'mkstemp' was not declared in this scope
int fd = mkstemp (filename);
^
Import mkstemp from gnulib.
