Pull assignment out of assert statement. If assert is a no-op, the assignment
won't be done.

Remove duplicate declaration of gd fonts; re-add extern. Without extern, thesewill be defined locally and uninitialized. We want these to bind to gdFontPtrs
defined in libgd.

Enable JSON on Windows build
The JSON module was not included in the Windows build because of some
errors. These errors were caused by two function from gvc not being added
to the Windows definition file. This is now resolved and JSON is added.

Use <type>_MAX instead of <type>_SIZE, rectangle.c
Instead of using the custom defined <type>_SIZE defines in
lib/label/rectangle.c function RectAra, we now use the defines
<type>_MAX from the standard library. The meaning is the same, but it is
more portable and requires less checks.

Remove `#ifdef _UWIN` block with hard path include
The header globals.h had an `#ifdef _UWIN` block at the top. This block
had an include with a hard path, which is a bad idea. Since it has
been 12 years since this block has been modified an UWIN isn't used in
the current build, we remove this block.

Remove `AC_HEADER_DIRENT` from configure.ac
The check `AC_HEADER_DIRENT` is no longer needed, as all current UNIX
systems have the correct version of this header. The checks and
corresponding define can be removed.

Remove `AC_HEADER_TIME` from configure.ac
This check is deprecated according to the official autoconf documentation,
it can safely be removed.
