The following program crashes g++1.35
================externcrash.cc=============
extern "C" {
/* structure used to specify fields in a 32-bit pixel */
union fbunit {
    unsigned int    packed;            /* whole-sale deal */
    struct {
        unsigned int    A:8;           /* unused, for now */
        unsigned int    B:8;           /* blue channel */
        unsigned int    G:8;           /* green channel */
        unsigned int    R:8;           /* red channel */
    }               channel;           /* access per channel */
