If LLVM's DejaGNU usage is the same as GCC's, I'll google or ask on the
MinGW mailing list how MinGW testers run the GCC testsuite, before
trying to fix something that maybe is not broken.

AFAIK, there is no "native" port of `bash' on Windows. If you plan to
use Cygwin's (or MSYS', which is a fork of Cygwin) you will discover
that it is quite tricky to work with non-Cygwin processes (including
MinGW's gcc) due to differences on directory structures, I/O, process
