Make pgwin32_putenv() probe every known CRT, regardless of compiler.

This extends to MinGW builds the provision for MSVC-built libraries tosee putenv() effects. Doing so repairs, for example, the handling ofthe krb_server_keyfile parameter when linked with MSVC-built MITKerberos. Like the previous commit, no back-patch.
