[Bug bootstrap/38580] New: Bootstrap broken on mingw32

[fxcoudert at gcc dot gnu dot org]

Bootstraping on i586-pc-mingw32 (with mingw-3.15.1, the latest version) is
broken by:

This same error happens at stage 2 and 3. Working around it by compiling gcc.c
(and only gcc.c) without -Werror, I can confirm that the rest of the bootstrap
then goes fine.

I'm adding Kai to the CC list. As he's now maintainer, he may want to help
here.

Ian Taylor said on IRC that -b/-V should use pex_one/exit instead of execvp.

Created an attachment (id=17052)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17052&action=view)
Replace execvp with pex_one in process_command

Patch uses pex_one as per Ian Taylor suggestion , but the error reporting may
need expansion.

------- Comment #5 from jakub at gcc dot gnu dot org  2009-01-09 09:36 -------
Seems to work on x86_64-linux.  The error message is different if the program
doesn't exist:
./xgcc -b nonexistent-target -B ./ -v
./xgcc: error trying to exec './nonexistent-target-gcc-4.4.0': execvp: No such
file or directory
from:
./xgcc -b nonexistent-target -B ./ -v
xgcc: couldn't run './nonexistent-target-gcc-4.4.0': No such file or directory
but I guess that's not a big deal.  When the program exists, it works just
fine.  If it works on mingw, can you post it to gcc-patches?

Ok, I agree that the error message shouldn't be here a big problem. Your patch
works for mingw-w64, so I have no objections.
