This fixed that problem, but then the linker fails to find some
functions, including all of the Qt functions. The exact same
configuration worked with gcc-2.95.2, and the Qt library is linked
with the same gcc-3.3 as lyx-1.3.3:
g++ -O -framework Carbon -framework OpenGL -framework AGL -framework QuickTime -o lyx
BufferView.o [...] mathed/.libs/libmathed.a insets/.libs/libinsets.a
frontends/.libs/libfrontends.a -L/usr/local/src/qt/lib -lqt
graphics/.libs/libgraphics.a support/.libs/libsupport.a -lz
../boost/libs/regex/src/.libs/libboostregex.a -L/sw/lib
../boost/libs/signals/src/.libs/libboostsignals.a ../intl/libintl.a -lc -lm
