# Change User Description Committed
#7 1315 Richard Geiger Changes preparing for an integrate back into //pubic/jam/...
#6 1313 Richard Geiger Cygwin jam porting: dance around bison and yyacc.
 Use
bison's -y flag to use yacc's output file naming conventions,
and don't use yyacc on systems whose SUFEXE is set ("the heathen").

=== computer.perforce.com:1666: Change 27145 by perforce@fork-cygwin on 2001/10/23 12:09:12

Noted as portability change in RELNOTES. - rmg
#5 1305 Richard Geiger Port new jam to run with just cxx compiler, 'cause we're
too cheap to buy the C compiler.

=== computer.perforce.com:1666: Change 21156 by PERFORCE@vulgar on 2001/03/12 16:17:08

This is a VMS portability change, but does touch code compiled on
other platforms.

Added to RELNOTES - rmg
#4 1258 Richard Geiger Flags to build jam debug/profiled (jam -sDEBUG=x, -sPROFILE=x).
Unix only.

=== computer.perforce.com:1666: Change 20000 by seiwald@golly-seiwald on 2001/01/11 08:36:00
#3 1241 Richard Geiger Split jam's built-in rules out to builtins.c from compile.c,
so that compile.c only deals with the language.

=== computer.perforce.com:1666: Change 19939 by seiwald@spice2 on 2001/01/08 22:55:10
#2 1240 Richard Geiger Split jam's pathsys.h from filesys.h, since they are really
two different pieces.

=== computer.perforce.com:1666: Change 19938 by seiwald@spice on 2001/01/08 21:46:33

Added note in RELNOTES about the internal code change - rmg
#1 1207 Richard Geiger Establish this branch to use for import of Perforce Jam.
//guest/perforce_software/jam/src/Jamfile
#4 556 Perforce staff Patch release jam 2.3.2: reverse NOCARE change.
 NOCARE once
again applies to targets with source and/or actions, so that
buildable header files get built.
#3 486 Perforce staff Jam 2.3.
 See RELNOTES for a list of changes from 2.2.x.

Just about every source file was touched when jam got ANSI-fied.
#2 3 Perforce maintenance Jam/MR 2.2.1 (fix for NT handle leak)
#1 2 laura Add Jam/MR 2.2 source
