Subject: [PATCH]    Fixed problem with returning -1 on error when the return
 value is a long long. Done by plugging both eax and edx with -1. This will
 clobber edx unnecessarily when the return value is only 32bit...though
 probably always an okay thing to do, it could stand a better fix.    This was
 the cause of gawk being broken (boy was THAT ever a subtle bug!!!).
