The Makefiles define DUMPBIN to be a path inside the VS2010 install, but some installs seem to have issues with the makefile logic not thinking it exists, but the path that the makefiles say does not exist, does exist.

This could be a problem with wildcard in GNU make, or something else having to do with CYGWIN.

Error like:
"Cannot find the DUMPBIN utility from path: C:/Programs/MicrosoftVisualStudio10.0/Common7/Tools//../../Vc/Bin/dumpbin.exe"
