RFC: Adding a check to the top level configure script for a binary-mounted cygwin-hosted build directory

Are the problems described in PR 4334 also present when building under 
MinGW or DJGPP ?  If not, then we can keep this new autoconf test as a 
Cygwin specific test.

If those problems are also present then I would agree with you that we 
need to fix the binutils build process.
