Bugzilla Bug 192685

Hello, 

in bug #178652, someone reported that qt-4.3 couldn't be compiled with gcc-3.4
on amd64. The reporter was able to switch to gcc-4, which fixed the problem for
him. 
However, there are still profiles which have gcc-4 masked (e.g.
hardened/amd64), and for these systems, bug #178652 hasn't been fixed yet. 

I will attach a patch for qt-4.3.1-r1.ebuild which adds the fix mentioned on
[1] to the ebuild (add -fno-gcse to C[XX]FLAGS in src/gui/Makefile)
The patch was tested successfully on the system with emerge --info shown below. 

Regards,
Milan

Make compiling qt-4.3 with gcc-3.4 possible

I'm not quite sure whether modifying an auto-generated Makefile in the middle
of src_compile is a good idea, but this way only the files in a single
directory a compiled with -fno-gcse. 

Please, don't file bugs about the same issue over and over again. If you want
to attach a patch, do it on the original bug. Thanks.
