Hello,

build fails here:

In file included from ./base/gxht_thresh.c:45:0:                                                                                               
/usr/lib/gcc/i686-pc-linux-gnu/4.5.3/include/emmintrin.h:32:3: error: #error "SSE2 instruction set not enabled"

My CPU is Athlon-XP and SSE2 instruction set is obviously absent.

MAKEOPTS="-j1" FEATURES="-distcc -ccache" emerge ghostscript-gpl
fails in the same way.

-DHAVE_SSE2 was mistakenly added to the compilation flags, because of malfunctioned sse2 check in configure script. Compilation test must be used instead of linking test. 

Proposed patch fixes this bug.

SSE2 patch must be applied before eautoreconf.

I've created an upstream bug, see URL.

Please confirm that it also fails when using sane(er) CLFAGS/LDFLAGS like:

CFLAGS="-march=native -O2 -pipe"
CXXFLAGS="${CFLAGS}"
LDFLAGS="-Wl,-O1 -Wl,--as-needed"

Hmm,

it compiles with my default CFLAGS/CXXFLAGS and simplified LDFLAGS="-Wl,-O1,--as-needed". Though, original LDFLAGS are formally valid.

Well I can't judge on this since your flags are quite.. huge and beyond my knowledge. But shouldn't at least -march be the same for CFLAGS and LDFLAGS? And at least my Atom CPU supports SSE2 hence perhaps the problem?

If you find out the problematic flag and if it's really not something unsupported or the like, please solve it upstream and reopen this bug.
