Обсуждение: pgsql: Blind attempt to fix _configthreadlocale() failures on MinGW.

Blind attempt to fix _configthreadlocale() failures on MinGW.

Apparently, some builds of MinGW contain a version of
_configthreadlocale() that always returns -1, indicating failure.
Rather than treating that as a curl-up-and-die condition, soldier on
as though the function didn't exist.  This leaves us without thread
safety on such MinGW versions, but we didn't have it anyway.
