Peter Eisentraut 3e908fb54f Fix compiler warnings around _CRT_glob ...

Newer compilers warned about

    extern int _CRT_glob = 0;

which is indeed a mysterious C construction, as it combines "extern"
and an initialization.  It turns out that according to the C standard,
the "extern" is ignored here, so we can remove it to resolve the
warnings.  But then we also need to add a real extern
declaration (without initializer) to satisfy
-Wmissing-variable-declarations.

(Note that this code is only active on MinGW.)
