FWIW, PROJ 4.6.0 compiled from source on Windows with MinGW gives the
"Linux" result above, while the version included in OSGeo4W gives the
"Windows" result.

However, I don't know if this is an issue with the compiler or the
runtime. MinGW uses msvcrt.dll, while the OSGeo4W version uses
msvcr71.dll. Attempting to use "-nodefaultlibs ... -lmsvcr71" with
MinGW ends up pulling in both msvcrt.dll and msvcr71.dll.
