XSB Src (SVN)-old

Now initializing dollar_var_psc on startup, along with other global pscs.

A bunch of coersions, fmt changes, type long to int (which eliminated
a long-standing warning from MSVC in 32-bit mode). I don't know why
some of these warnings just showed up now (maybe Michael's cygwin
compiler invocation change?), but good to have them.

made -mno-cygwin to be off by default, since gcc has dropped support for this years ago. If somebody badly wants to use gcc 3.*, he'll have to use configure --enable-no-cygwin.

forgot to comment out example code

mainly added external .o files for creation of the executable XSB file. Previously it was only for the xsbmod target.
Made dollar_var_psc available externally.

added the ability to statically link XSB with external obj files for windows also

Moved intern_cpred() to psc_xsb.c

A few coersions to quiet my compiler warnings.

Move to after end of switch of a "return TRUE;" commented to be at end
of switch in table_inspection_function, but wasn't. My compiler
warnings pointed it out.

Added only a couple of commented-out lines of code, but useful when debugging
(at least for my archaic techniques.)

Commented out code used only in commented out code, to quiet compiler
warnings.
