XSB Src (SVN)-old

Comment out declaration of unused variable (to quiet compiler.)

Changed \x and \<num> (for octal) escapes in strings to allow termination
by first non hex (oct) digit.
Also changed to recognize [] and {} as tokens, so they can appear as functors.

Fixed nasty bug in deleteoutedges, where an iterator value that needed to be reinitialized each time an inner loop was entered wasnt properly reinitialized.

Add condition to properly parse obscure use of infix and prefix op,
e.g., a - - - b. (Thanks, Ulrich. I guess I don't have better things
to do with my life...)

Fixed \u escapes in strings to support trailing \ to end hex-digit sequence.

asked to ignore config.log files in svn
updated windows banners

Fixed bug in w1252_char_to_codepoint (pointed out, and fixed, by Michael).
It needed to increment the char pointer.

Also fixed a use of it in odbc_xsb.c (where it had incremented the
pointer itself, but now should not.)

Made unary - operator fy (as in standard.)

Added through-tracing of \+.

Cleaned-up defined but not exported, and exported but not defined.
