Separate out function and function pointer attributes, as not all
versions of all compilers support both.
Have macros related to function attributes auto-generated by
autoheader. As a result, rename config.h.in to unconfig.h, to make it
more obvious that it is really intended to be included from some C
programs.

[f]stat on Windows is messy: we need to use _stati64 for maximum
compatibility, but because there is a bunch of stuff wrapped in
macros, autoconf sometimes gets the wrong answers.

On Windows we need to use _stati64/_fstati64 in order to handle large
file sizes, but the handling was broken in the canned MSVC++
configuration. Clean it up and fix it.
This addresses BR 3392398.

OpenWatcom still doesn't have proper support for 64-bit switch
statements. Hack around it in a truly vile way.

Move the canned OpenWatcom configuration file to config/watcom.h.
Also exclude config/config.h from being a dependency for MSVC.

Apparently, at least on some OS/2 compilers, <sys/types.h> needs to be
included for off_t to be defined. This seems like a generically good
idea to include this header whenever it is available.
Remove reference to <types.h>. This was supposedly for MSVC, but
there is no actual evidence that it is useful beyond <sys/types.h>.

Instead of trying to do hacks in the Makefiles, define header files
for specific compilers if they can't use autoconf. Currently defined
for Microsoft Visual Studio, based on MSDN documentation. It is
currently untested.
