Use HAVE_STDLIB_H instead of STDC_HEADERS macro. * jartool.c: Likewise. * compress.c: Likewise. Revision 1.9 2001/10/12 00:49:42 bryce * jatool.c (extract_jar): Account for null termination when determining whether to expand "filename". Revision 1.8 2001/08/29 01:35:31 apbianco 2001-08-28 Alexandre Petit-Bianco <apbianco@redhat.com> * jartool.c (add_to_jar): Return 1 if `stat' initialy failed. Fixes PR java/3949.

Revision 1.6 2001/07/04 18:33:53 tromey Modified from patch by Julian Hall <jules@acris.co.uk>: * jartool.c (errno): Conditionally declare. (O_BINARY): Conditionally define. (main): Use open, not creat. Use O_BINARY everywhere. (make_manifest): Use O_BINARY. (add_to_jar): Likewise. Revision 1.5 2001/05/03 21:40:47 danglin * jartool.c (jt_strdup): New function. (get_next_arg): Use jt_strdup instead of strdup. Revision 1.4 2000/12/28 21:47:37 robertl 2000-12-28 Robert Lipe <robertl@sco.com> * jartool.c (MAXPATHLEN): Provide if not defined.

Make functions static. Cast ctype function argument to `unsigned char'. Add parens in if-stmts. Constify. (Usage): Change into a macro. (jargrep): Remove unused parameter. * jartool.c: Constify. Add parens in if-stmts. Align signed/unsigned char pointers in functions calls using casts. (rcsid): Delete. (list_jar): Fix printf format specifier. (usage): Chop long string into bits. Reformat. * pushback.c (rcsid): Delete. Revision 1.2 2000/12/13 18:11:57 tromey * jartool.c (extract_jar): Use strchr, not index. Revision 1.1 2000/12/09 03:08:23 apbianco 2000-12-08 Alexandre Petit-Bianco <apbianco@cygnus.com> * fastjar: Imported. Revision 1.5 2000/08/24 15:01:27 cory Made certain that fastjar opened the jar file before trying to update it with the -u option. Revision 1.4 2000/08/24 13:39:21 cory Changed +'s to |'s in jartool.c to insure there was no confusion with sign when byte swapping. Better safe than sorry. Revision 1.3 2000/08/23 19:42:17 cory Added support for more Unix platforms. The following code has been hacked to work on AIX, Solaris, True 64, and HP-UX. Added bigendian check. Probably works on most big and little endian platforms now. Revision 1.2 1999/12/06 07:38:28 toast fixed recursive archiving bug Revision 1.1.1.1 1999/12/06 03:09:34 toast initial checkin.. Revision 1.22 1999/10/12 19:45:13 burnsbr adding patch to fix compat problem Revision 1.21 1999/05/10 09:15:49 burnsbr fixed manifest file version info Revision 1.20 1999/05/10 08:53:16 burnsbr *** empty log message *** Revision 1.19 1999/05/10 08:30:39 burnsbr added extract / listing code Revision 1.18 1999/04/28 04:24:29 burnsbr updated version Revision 1.17 1999/04/28 04:21:23 burnsbr added support for -C dir-changing flag..

Revision 1.10 1999/04/22 02:35:23 burnsbr added more manifest support, about 75% done now. Replaced all the redundant shifts and bit-logic with a macro or two, making the code easier to read.
