Bug 126839 – games-arcade/ssc-0.8: fix compilation with gcc-4.1

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description TGL 2006-03-19 10:43:17 UTC]

When compiling this game with gcc-4.1, I get a few warnings.  But the ./configure script forces -Werror in CXXFLAGS, and thus the while build process fails:

I will attach an ebuild patch to sed out this -Werror flag. Hope it is an acceptable workaround, since i don't know C++ enough to actually fix all the warnings.
