NetBSD-i386-current uses gcc version 3.3.3. This version is known to have a=
several of bugs that forced me to make use of gcc version 3.4.4 from the=20
pkgsrc tree, e.g. pkgsrc/math/fftwf will segfault with sse optimized=20
binaries. I also have a local copy of gcc4-ada in order to participate in A=
related projects.

I'm in support of Georges enquiry and like to propose ditching gcc3, keepin=
gcc3.4 and creating gcc4 to reflect current developments.

Can someone enlighten me why NetBSD is stuck on the buggy gcc-3.3.3 and did=
upgrade to gcc-3.4.4?
