The message "WARNING: Could not compile gcc.dg/compat/struct-layout-1 generator
" is "odd". The gcc.log _claims_ it is using the OS gcc to compile:
# ls -l /opt/gcc-4_3-build/gcc/testsuite/gcc/gcc.dg-struct-layout-1_generate
ls: /opt/gcc-4_3-build/gcc/testsuite/gcc/gcc.dg-struct-layout-1_generate: No

When I cut-and-paste the gcc command from the log the generator compiles OK.
The testsuite works on 4.2.0 i686-pc-cygwin and 4.2.1 i686-pc-linux-gnu.
Point 1): Having the testsuite fail with this warning denies the testsuite from
running a whole battery of tests that the generator creates. One warning
_might_ cover-up many _possible_ errors if the test were ran (or hide many
sucesses).
Point 2): (Retorical Questions) Why do we use "gcc" ? - The OS's "gcc". Which
version are we using, do we care? Can it actually compile the tests?
We _ought_ to use gcc/xgcc ! - then we know which version of gcc we are using.
If xgcc can not compile the generator then _IT_ is at fault. If the OS's gcc
can not compile the generator then does that _actually_ matter - no.
If the program is so trivial that any compiler can compile it then why not have
xgcc do it. That makes the "warning" into an error _IF_ it fails, if it
succeeds then it is a "pass" and not a warning.
The rest of the tests can then get a chance to run instead of being denied
simply because the OS's gcc did not compile the file.
Another problem occurs immediatly after:

The testsuite _CLAIMS_ it could not open the file but actually it is an ICE.
