Subject: Ada: Fix GNU/Hurd priority range
X-Git-Tag: basepoints/gcc-16~3441
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d56e82d1a9370b33d91ccdd7289e854f6604a563;p=thirdparty%2Fgcc.git

Ada: Fix GNU/Hurd priority range

GNU/Mach currently uses a 0..63 range.

gcc/ada/ChangeLog:

	* libgnat/system-gnu.ads: New file.
	* Makefile.rtl (x86-gnuhurd): Use libgnat/system-gnu.ads instead of
	libgnat/system-freebsd.ads.
