C Compiler cannot create executables on SUA/Interix

Whenever I try to build an application with Interix's GCC on Windows, this is what happens:

/tmp/grep-2.5.4-src/build$ ../configure --build=x86_64-pc-interix6
checking for a BSD-compatible install... /bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ../install-sh -c -d
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking build system type... x86_64-pc-interix6
checking host system type... x86_64-pc-interix6
checking for gawk... (cached) gawk
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

To me it looks like the problem isn't with the compiler, but rather with the configure file.

How can I fix it so that it works with SUA?

config.log:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU grep configure 2.5.4, which was
generated by GNU Autoconf 2.61.  Invocation command line was

  $ ../configure --build=x86_64-pc-interix6

configure: exit 77

It's looking for cc1 as a compiler and can't find it, which is why it's failing.

gcc: error trying to exec 'cc1': execvp: No such file or directory.

So it's not that the compiler can't create executables, but that it can't find it. gcc invokes cc1. Check your system for it, or perhaps your PATH.
