I've been playing around trying to build the system set with Clang[1]. dev-libs/gmp fails a configure check out of the box causing it not to build. The build error is related to converting the source using ansi2knr; the call to ansi2knr is missing in the commandline, making the build fail. The configure check controlling ansi/knr compile modes is failing due to some over-eager style checks by clang, erroring on the main function signature (argv is declared char *argv, not char **argv). [1] http://clang.llvm.org/ Reproducible: Always Steps to Reproduce: 1. $ CC=/path/to/clang emerge -av --oneshot dev-libs/gmp Actual Results: libgmp fails to build, with a bad command for ansi2knr conversion. Expected Results: libgmp to be built and installed successfully Patch and a new ebuild to fix this are attached. Note the patch doesn't address the missing call the ansi2knr, it instead fixes the configure script to make clang pass the ANSI test.

the real bug is lack of quoting in acinclude.m4. it tries to use *argv[], but the [] is consumed by m4. gmp upstream has fixed this already in their mercurial repo: http://gmplib.org:8000/gmp/rev/43784518850d when posting ebuilds, please attach diffs and not entire files http://sources.gentoo.org/dev-libs/gmp/gmp-4.3.1.ebuild?r1=1.9&r2=1.10
