Test redone.
g++ (GCC) 3.4 20031010 (experimental)
real 24m20.049s
user 22m17.930s
sys 1m45.420s
ls -l src/lyx-xforms src/lyx-qt

So a lot better, but still a bit disappointing, since the compilation
time is still increasing.
PS. Gcc configured like this:
../configure --prefix=/opt/gcc34 --enable-languages=c,c++ --disable-checking
