Subject: make signgam a weak alias for an internal symbol
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=1a3dce4184895be87b32dcb7c891c5cb87d88a95

make signgam a weak alias for an internal symbol

otherwise, the standard C lgamma function will clobber a symbol in the
namespace reserved for the application.
