Thanks. With this patch, TeXmacs-1.0.7.7 compiles.

When I start it, it segfaults immediately (no messages in the terminal 
window before segfault). OK, to debug it, I re-compiled it with 
CXXFLAGS="-O0 -g". And it works! The problem seems to be with my usual 
CXXFLAGS="-O2 -march=native -pipe". But 99.9% of software compile and run 
with this usual CXXFLAGS. What's so special about TeXmacs? My gcc is 
4.4.5.
