Summary	02732: SDLMAME fails to build on PPC when using GCC 4.3.2 and Altivec support enabled
Description	Hi, I'm a Gentoo Linux user on PPC and I'm not able to compile SDLMAME under certain circumstances. I've tried SDLMAME 0.127, SDLMAME 0.128 and SDLMAME 0.128u5 with the same results. My CFLAGS are the following: CFLAGS="-O2 -mcpu=7450 -maltivec -mabi=altivec -fno-strict-aliasing -pipe" If I use GCC 4.1.2, I can compile SDLMAME with no problems. If I use GCC 4.3.2, SDLMAME fails to build. To build SDLMAME with GCC 4.3.2, I have to change "-maltivec" to "-mno-altivec" in my CFLAGS.
Steps To Reproduce
Additional Information	This is the error that I get: [...] Compiling src/mame/drivers/gaelco2.c... Compiling src/mame/machine/gaelco2.c... Compiling src/mame/video/gaelco2.c...
