-fomit-frame-pointer is not used). This is mostly moot for -current because gcc-3 does the alignment (slightly incorrectly) in main(). This patch is intended for easy MFC'ing and should be backed out in -current soon since it causes compiler warnings and better fixes are possible in -current. The best fix is to do nothing here and wait for gcc to do stack alignment right. gcc-3 aligns the stack in main(), but does it too late for main()'s local variables and too late for anything called before main(). A misaligned stack is now more than an efficiency problem, since some SSE instructions in some or all (hardware) implementations trap on misaligned operands even if alignment checking is not enabled.
