just added a hack from the mailing list, I'll take no credits for it.

What list is that? I've tried doing this before. A patch/sed to enable CFLAGS isn't the problem, it's that the default flags include -Wall and with -O3 or in some other combinations it enables some flags that require several hundred MBs of ram per file being compiled. With make -j2 added, it's a recipe for disaster, especially on pcc I think. It's in info gcc somewhere, at least it was for gcc 2.x (perhaps it's been fixed since then). Of course we could remove -Wall since we "know" that the source compiles cleanly. But I'm not sure I want to do it snice noone ever proved that added optimizations actually change anything in qt's preformance! I'll return to this later.
