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.
using NC_MPIIO or NC_MPIPOSIX explicitly is not necessary.
These 2 subroutines call NC_create() and NC_open() with argument
useparallel set to 1, which should be used to tell which I/O
driver to use underneath.
unlimited dimension hanging. Extending the size of an unlimited
dimension in HDF5 must be a collective operation, so now an error is
returned if trying to extend in independent access mode.

contain as little file-type specific info as possible. It
modifies especially libsrc so that all of the netcdf-3 data
that used to be in struct NC is now kept in a separate chunk
of data pointed to by the struct NC. This makes all of
current protocols consistent: netcdf-3, netcdf-4, and dap.
