This is already fixed on the trunk.  The release branch insists on
"-mingw32" suffix (of course, you can hack it).

The advice to use --prefix is there for a reason.  My advice is to
stay away of the MSYS tree, so that your absolute file names always
include an explicit drive letter, as in /x/foo/bar.  Otherwise, you
risk passing just /foo/bar to MinGW programs that won't grok it.
