I just tried to compile the package fceu-0.98.25-1.7
with the GNU C++ compiler version 4.4 snapshot 20081212.
The compiler appears to get into a long or possibly infinite loop.
I tried compiling with flag -O2 and that took 40 seconds or so.
With flag -O3, compilation did not finish in over seven minutes on
an otherwise idle machine.
Preprocessed source code attached. Flag -O3 required.
