I doubt MinGW has overridden popen() at runtime; that would be contrary to its design criteria. The headers, however, are MinGW territory. MinGW declares both _popen() and popen() as functions. MinGW-w64, a project more distinct from MinGW than it sounds, uses "#define popen _popen": MinGW: http://sourceforge.net/p/mingw/mingw-org-wsl/ci/master/tree/include/stdio.h#l467 MinGW-w64: http://sourceforge.net/p/mingw-w64/code/HEAD/tree/trunk/mingw-w64-headers/crt/stdio.h#l496 Building with any recent MinGW-w64, 32-bit or 64-bit, gets the reported warnings; building with MinGW proper does not. -- Noah Misch EnterpriseDB http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
