done in the very same moment you asked me to do this ;)

Reporter: please unrice your cflags and try again.
Try (in one line):
CFLAGS="-march=athlon-xp -O3 -pipe" CXXFLAGS="-march=athlon-xp -O3 -pipe"
LDFLAGS="" emerge -1v =dev-java/gnu-classpath-0.93

Apart from that, I also couldn't emerge gnu-classpath with this:
USE="alsa cairo -debug -dssi -examples -gconf gtk nsplugin xml" emerge -1v
=dev-java/gnu-classpath-0.93

Build.log attached

This is an upstream bug. gnu-classpath doesn't compile with -O3 it seems.
Changing it to -O2 while waiting for upstream to fix this.

Indeed, changing -O3 to -O2 circumvents this problem but the next one comes
with "nsplugin" useflag, which is described in bug #168780 and which Peter
Alfredsen also suffers from.
