netcdf-c/include/nc_provenance.h
Dennis Heimbigner 1a7531392f Make the netcdf-c library compile with gcc -ansi.
Primary fixes to get -ansi to work.
1. Convert all '//' C++ style comments to /*...*/ or to use #if 0...#endif
2. It turns out that when -ansi is specified, then a number of
   functions no longer are defined in the header -- but they are still
   in the .so file.<br>
   The big example is strdup(). So, added code to include/ncconfig.h to define
   externs for those missing functions that occur in more than one place.
   These are enabled if !_WIN32 && __STDC__ == 1 (__STDC__ is supposed to
   be the equivalent compile time flag to -ansi). Note that this requires
   config.h (which references ncconfig.h) to be included in files where it is
   currently not included. Single uses will be only in the file that uses them.
3. Added mmap test for the MAP_ANONYMOUS flag to configure.ac. Apparently
   this is not always defined with -ansi.
4. fix some large integer constants in nc_test4/tst_atts3.c and nc_test4/tst_filterparser.c
   to avoid compiler complaints.
5. fix a double constant in nc_test4/tst_filterparser.c to avoid compiler complaints.

[Note I suspect #4 and #5 will be a problem on big-endian machines, but we have no way to test]

Misc. Changes:
1. convert more instances of _MSC_VER to _WIN32.
2. added some debugging code to include/nctestserver.h
3. added comment about libdispatch/drc.c always being compiled.
4. modify parser generation in ncgen to remove unneeded files.
