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.
Update utf8proc.[ch] to use the version now
maintained by the Julia Language project
(https://github.com/JuliaLang/utf8proc/blob/master/LICENSE.md).
The license for the previous version was
unacceptable for the Debian and Ubuntu release
systems. The new version both updates the code
and addresses the license issue.
It turns out that the utf8proc software we are using
was turned over to the Julia Language developers
and the license terms changed to allow modification.
(https://github.com/JuliaLang/utf8proc/blob/master/LICENSE.md).
So the fix here is as follows:
1. Wrap the library with a fixed interface: libdispatch/dutf8.c
and include/ncutf8.h.
2. Replace the existing utf8proc code with the new version
from https://github.com/JuliaLang/utf8proc.
3. Add a couple more test cases: nc_test/tst_utf8_validate.c
and nc_test_utf8_phrases.c. If/when I can find a usable
normalization test, I will incorporate that later.
