X-Git-Tag: basepoints/gcc-15~4383
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=08ba7e8b98e71d72c2bb3860f8d3642ce380afdf;p=thirdparty%2Fgcc.git

gcc.misc-tests/linkage-y.c: Compatibility with C99+ system compilers

This program is compiled with an installed "cc" compiler, not the
built GCC compiler, so it should be as compatible as possible across a
wide range of compilers.

gcc/testsuite/

	* gcc.misc-tests/linkage-y.c (puts): Declare.
	(main): Add int return type and return 0.
