Re: Interix cc compiler suddenly fails tests in new 64bit SUA 6.1 RC1

It looks like your compiler is generating a .o file even when it
is invoked with the -E option.  Perhaps you can track it down
by debugging the "configure" script.  Try running this:

cd tests
./testsuite -v -d 145

and then look at what's in the tests/testsuite.dir/145 directory.
