>Description:
see below

code works with gcc-3.0 and gcc-3.3 snapshot
also works with gcc-3.2 with -O1

>How-To-Repeat:
-------8< cut here 8<---------
inline int fixfloor (long x) { if (x >= 0) return (x >> 16); else return ~((~x) >> 16); }
inline int fixtoi (long x) { return fixfloor(x) + ((x & 0x8000) >> 15); }
int foo(long x, long y) { return fixtoi(x*y); }
