This builds successfully, with minor problems, on native MS-Windows
using mingw.org's MinGW.  The minor problems I found are:

1. A compilation warning in Gnulib's select.c -- reported to the
Gnulib folks.

2. A compilation warning in symtab.c:

       CXX    symtab.o
     symtab.c: In member function 'bool info_sources_filter::matches(const char*) const':
     symtab.c:4247:28: warning: 'to_match' may be used uninitialized in this function [-Wmaybe-uninitialized]
      4247 |       if (m_c_regexp->exec (to_match, 0, NULL, 0) != 0)
	   |           ~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~

I guess we need a 'default:' case there?  Or maybe initialize
'to_match' with some suitable value?

Thanks.
