Subject: [libstdc++-v3] [rtems] enable filesystem support
X-Git-Tag: basepoints/gcc-16~8632
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5955c18dfb970740d55d432aeee5cb5a6f51cf65;p=thirdparty%2Fgcc.git

[libstdc++-v3] [rtems] enable filesystem support

mkdir, chdir and chmod functions are defined in librtemscpu, that
doesn't get linked in during libstdc++-v3 configure, but applications
use -qrtems for linking, which brings those symbols in, so it makes
sense to mark them as available so that the C++ filesystem APIs are
enabled.


for  libstdc++-v3/ChangeLog

	* configure.ac [*-*-rtems*]: Set chdir, chmod and mkdir as
	available.
	* configure: Rebuilt.
