Subject: Darwin, crts: Fix a build warning.
X-Git-Tag: basepoints/gcc-13~3359
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7a300b413a62e1989bd89064fd5594aabe371d3a;p=thirdparty%2Fgcc.git

Darwin, crts: Fix a build warning.

We have a shim crt for Darwin10 that implements functionality
missing in libSystem. Provide this with a prototype to silence the
warning about this.

libgcc/ChangeLog:

	* config/darwin10-unwind-find-enc-func.c: Include libgcc_tm.h.
	* config/i386/darwin-lib.h: Declare Darwin10 crt function.
