 Log Message:
 Update to 1.4.2, based on patches by Mayuresh in PR 47325.
 Set LICENSE while here.
 Change in GNU Prolog version 1.4.2:
 * fix a bug in the x86/NetBSD port

 * modify the compiler include/1 directive handling
   (if the file to include is not found, seach in directories of parent 
 * modify atom table management (its size can be defined via env. var MAX_ATOM)
 * fix a bug with soft-call inside a meta-call
 * implement term_hash/2 and term_hash/4. Bacward incompatibility:
   new_atom/3 and and atom_hash/2 no longer exists.
 * fix some little bugs with 64 bits (e.g. stream id)
 * modify the FD solver to handle very long computations
 * fix a bug in the compiler (unification with fresh vars in the body)
 * fix a bug with *-> containing ! in the test part (! was not local to the

 * fix some problems/bugs on 64 bits machine
 Change in GNU Prolog version 1.4.1:
 * improve signal handling
 * add an option --wam-comment to gplc and pl2wam
 * fix multifile directive (works now with an empty predicate as required by 
 * fix absolute_file_name to expand ~ using HOMEDRIVE and HOMEPATH under windows
   if HOME is not defined

 * add write_term option variable_names
 * add built-in predicates between/3 and succ/2
 * fix bug in the DCG expander

 * recognize escape sequence \s (space) and \e (escape) if strict_iso is off
 * add error detection in length/2 if given length is negative
 * add built-in predicates maplist/2-5
 * fix a regression bug in the FD solver about sparse domains
 * increase size of FD internal stacks and fix memory leak
 * port to x86_64/Darwin (Mac OS X) - many thanks to:
   Ozaki Kiichi <>
 * fix a bug in x86_64 with --disable-regs
 * fix a bug when consulting a file under Win XP/Vista 32 bits
 * fix a bug when consulting a file using '$VAR'(N) or '$VARNAME'(A)
 * fix a bug in new_atom/1-2 which returned duplicates
 * fix a bug in write/1 when an empty atom is passed
 * improve portray_clause (numbervars and space before final dot)
 Change in GNU Prolog version 1.4.0:
 * GNU Prolog is now licensed under a dual license LGPL or GPL
 * port to x86_64/MinGW - many thanks to:
   Jasper Taylor <> (see src/WINDOWS64)
 * port to x86_64/MSVC (see src/WINDOWS64)
 * add a configure option to control Windows HtmlHelp
   --disable-htmlhelp or --enable-htmlhelp[=static/dynamic]
 * improve a lot (and fix some bugs in) the Windows GUI Console
 * change location of gprologvars.bat under Windows (in install directory)
 * increase default stack sizes (32Mb for heap, 16Mb for others)
 * change the default setting for flag strict_iso: it is on now
 * add control constructs to the predicate table
 * modify predicate_property/2 (built_in_fd ==> built_in, add control_construct)
   only accepts a Head (a callable) (no longer a predicate indicator)
 * fix a bug in the compiler (bad unification with singleton variable)
 * fix a bug with strict_iso flag (was not passed to consult)
 * add shebang support using #!/usr/bin/gprolog --consult-file
 * modify the mangling scheme for future module support (see hexgplc)
 * fix write_term default options (now numbervars(false) and namevars(false))
 * fix read/1: tab and newlines are not accepted inside single/back/double 
quoted tokens
 * add additional errors to compare/3 and keysort/2
 * accept space under the top-level (same as ;)
 * modify portray_clause/1-2 to add a newline at the end of the output
 * add acyclic_term/1 (compatibility only since GNU Prolog does not handle 
cyclic terms)

var name
 * rename evaluable functor atan/2 as atan2/2 and >< as xor
 * add evaluable functor div/2

 * add some type tests on chars and codes (in number_chars/2, number_codes/2,..)
 * fix some little bugs in the parser
 * add meta_predicate property to predicate_property/2

 * allow rounding functions to accept an integer if strict_iso is off
 * group all examples under a new directory 'examples'
 * fix a bug in read_from_codes/2 and number_codes/2
 * improve speed of built-in predicates on list (append, member, reverse,...).
 * improve CTRL+C handling under the top-level
 * add is_list/1 (same as list/1)
 * add Prolog flags: dialect, home, host_os, host_vendor, host_cpu,
   host, arch, version, version_data, unix, argv
 * add preprocessor directives if/1 else/0 elif/1 endif/0

 * improve randomize/0 (more different values on consecutive calls)
 * relax the lexer to also accept 0'' (ISO requires 0''' or 0'\') is strict_iso
