[Bug bootstrap/22259] New: spawnv cannot execute gcc/as

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Building gcc on i686-pc-mingw32 fails with:

/home/FX/ibin/./gcc/xgcc -B/home/FX/ibin/./gcc/ -B/mingw/i686-pc-mingw32/bin/
-B/mingw/i686-pc-mingw32/lib/ -isystem /mingw/i686-pc-mingw32/include -isystem

executable: C:/msys/1.0/home/FX/ibin/gcc/cc1.exe
executable: C:/msys/1.0/home/FX/ibin/gcc/as
xgcc.exe: _spawnv: No such file or directory

[lines beginning with "executable:" are debug statements printing the executable
argument to pex_win32_exec_child, in libiberty/pex-win32.c]

In fact, xgcc cannot be used. It tries to execute gcc/cc1.exe, which works fine,
then gcc/as. gcc/as is a script, and not a real win32 executable program. Thus
the spawn fails.

I don't know when this stopped to work. Seems that "before", the assembler was
called directly and not by this script. Does someone know when this changed, and
does someone have an idea on how to fix this?
