Bug description

MSVC compiler option can begin with '-' or '/', i.e. "cl -nologo ..." is the same as "cl /nologo ...", usually using either works.

But in msys, it seems '/' is somehow reinterpreted, so the build will fail, but changing '/' to '-' will work.

Steps to reproduce

  1. Install VS2010 (or VS2012), msys and flexdll
  2. Start a VS2010 (or VS2012) command line
  3. Navigate to c:\msys, start msys shell
    4, In msys shell, navigate to ocaml source code folder c:\ocaml_trunk
  4. Use build process described in README.win32

The build will fail.

Apply the attached diff to source code (from SVN trunk), build again, it will work.

Need to make sure this will not break one of the other Windows ports.

Note that the compilation is intended to be done in a cygwin shell rather than an msys shell.

I'm applying this patch and CI will tell us if it breaks compilation under cygwin shell.

CI testing went well. This is fixed in 4.02 branch (commit 15362).
