Building the trunk into an empty directoy with
"$GCCDIR/configure" --enable-languages=c,fortran
--prefix=/projects/tob/gcc-trunk && make && make install
on an openSUSE 10.2rc2 system fails with
'cc1: error: unrecognized command line option "-Wno-overlength-strings'.
This is with "make" since I had the feeling "make -j2".
Yesterdays build with r119277 was still ok, the error occurs with r119303 up to
r119311. Building GCC 4.2 on the same machine works.

cc1: error: unrecognized command line option "-Wno-overlength-strings"
There are three cc1:
./gcc/cc1
./stage1-gcc/cc1
./prev-gcc/cc1
And doing
./gcc/cc1 -quiet -Wno-overlength-strings < /dev/null
gives no error. (and no other cc1 is in the path.)
If I do now manually make, some files are compiled again, the compilation
succeeds but with make install I get immediately the "-Wno-overlength-strings"
error again.
which gcc returns:
/usr/bin/gcc
which is 4.1.2 20061115 (prerelease) (SUSE Linux), which also happily accepts
"-Wno-overlength-strings".
I cannot reproduce it anymore at the moment, but I also had at some point
inbetween:
xgcc: error trying to exec 'cc1': execvp: No permission.
(No of pty is also ok: 7 vs. 4096)
