globbing not switched off? interferes with substring matching

[claus]

On windows, ghc-pkg needs to be linked with a CRT_noglob.o (setting _CRT_glob to 0), so that it does not attempt its own globbing.

That does not seem to happen anymore (no sign of CRT_noglob in the  build log).

Result is that substring matching does not work correctly. The effect seems to be masked in the testsuite because the substring matches there happen to expand to themselves (no matching files in the current directory):

In a cmd.exe:

>ghc-pkg --version
GHC package manager version 6.12.3

>dir
 Volume in Laufwerk C: hat keine Bezeichnung.
 Volumeseriennummer: 6A99-2261

Thanks for the report; fixed:
