Alan,

sorry for that. I have the following defines in my local headers
(which aren't standard) and I will prepare a patch for lto-plugin.c
for this.
If you define '#define WEXITSTATUS(w)    (((w) >> 8) & 0xff)' and
'#define WIFEXITED(w)      (((w) & 0xff) == 0)', the build will be
then successful.

For win32 the result of status can be SIGABRT in the lower 8-bits (if
child got a signal), or in the upper 8 bit the exit-code.

Regards,
Kai
