try CFLAGS="-O2" if that works for you, I will alter the ebuild. liboil is not benefited from all the funky flags coz it is just assembly code, it detects your platform itself and runs the correct asembly code routines.
I already use '-O2' in my CFLAGS. My impression is rather that some expressions (or makros) are not correctly defined for my platform. Maybe this is a problem with some 'if' or 'ifdef' precompiler commands (potentially in a header file)?
what I meant is comment out your current CFLAGS and just have O2 in them.
I did that. The same error still appears (see below). I still think that part of a declaration does not get included because of a conflict with 'if' or 'ifdef' precompiler commands. powerpc-unknown-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I../.. -Wall -Wa,-mregnames -D_BSD_SOURCE -D_GNU_SOURCE -I../.. -O2 -O2 -MT libpowerpc_la-conv.lo -MD -MP -MF .deps/libpowerpc_la-conv.Tpo -c conv.c -fPIC -DPIC -o .libs/libpowerpc_la-conv.o conv.c:78: error: syntax error before '*' token conv.c: In function `clipconv_s8_f32_powerpc': conv.c:78: error: `dst' undeclared (first use in this function) conv.c:78: error: (Each undeclared identifier is reported only once conv.c:78: error: for each function it appears in.) conv.c:78: error: `src' undeclared (first use in this function) conv.c:78: error: `n' undeclared (first use in this function) conv.c:78: error: `src_stride' undeclared (first use in this function) conv.c:78: error: `dst_stride' undeclared (first use in this function) conv.c: At top level: conv.c:79: error: syntax error before '*' token conv.c: In function `clipconv_u8_f32_powerpc': conv.c:79: error: `dst' undeclared (first use in this function) conv.c:79: error: `src' undeclared (first use in this function) conv.c:79: error: `n' undeclared (first use in this function) conv.c:79: error: `src_stride' undeclared (first use in this function) conv.c:79: error: `dst_stride' undeclared (first use in this function) ... ... make[3]: *** [libpowerpc_la-conv.lo] Error 1 make[3]: Leaving directory `/var/tmp/portage/liboil-0.3.7/work/liboil-0.3.7/liboil/powerpc' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/var/tmp/portage/liboil-0.3.7/work/liboil-0.3.7/liboil' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/liboil-0.3.7/work/liboil-0.3.7' make: *** [all] Error 2 !!!

If you need support, post the topmost build error, and the call stack if relevant.
I was having this problem also, it has been taken care off by the liboil people. When replacing conv.c by revision 1.3 that can be find in their CVS, http://cvs.freedesktop.org/liboil/liboil/liboil/powerpc/conv.c?rev=1.3&view=markup this emerge builds without any issue! An update to this package in the portage tree is the solution for this bug in PPC! Sheers!!! :)
*** Bug 122106 has been marked as a duplicate of this bug. ***
fixed in portage now thx
