Revision 1.48 2000/01/23 16:36:37 peter
* better auto RTL dir detection
Revision 1.47 2000/01/20 00:23:03 pierre
* fix for GetShortName, now checks results from Win32
Revision 1.46 2000/01/07 01:14:27 peter
* updated copyright to 2000
Revision 1.45 2000/01/07 00:08:09 peter
* tp7 fix
Revision 1.44 2000/01/06 15:48:59 peter
* wildcard support for directory adding, this allows the use of units/*
in ppc386.cfg
Revision 1.43 2000/01/04 15:15:50 florian
+ added compiler switch $maxfpuregisters
+ fixed a small problem in secondvecn
Revision 1.42 1999/12/22 01:01:48 peter
- removed freelabel()
* added undefined label detection in internal assembler, this prevents
a lot of ld crashes and wrong .o files
* .o files aren't written anymore if errors have occured
* inlining of assembler labels is now correct
Revision 1.41 1999/12/20 23:23:28 pierre
+ $description $version
Revision 1.40 1999/12/20 21:42:34 pierre
+ dllversion global variable
* FPC_USE_CPREFIX code removed, not necessary anymore
as we use .edata direct writing by default now.
Revision 1.39 1999/12/08 10:40:00 pierre
+ allow use of unit var in exports of DLL for win32
by using direct export writing by default instead of use of DEFFILE
that does not allow assembler labels that do not
start with an underscore.
Use -WD to force use of Deffile for Win32 DLL
Revision 1.38 1999/12/06 18:21:03 peter
* support !ENVVAR for long commandlines
* win32/go32v2 write short pathnames to link.res so c:\Program Files\ is
finally supported as installdir.
Revision 1.37 1999/12/02 17:34:34 peter
* preprocessor support. But it fails on the caret in type blocks
Revision 1.36 1999/11/18 15:34:45 pierre
* Notes/Hints for local syms changed to
Set_varstate function
Revision 1.35 1999/11/17 17:04:59 pierre
* Notes/hints changes
Revision 1.34 1999/11/15 17:42:41 pierre
* -g disables reloc section for win32
Revision 1.33 1999/11/12 11:03:50 peter
* searchpaths changed to stringqueue object
Revision 1.32 1999/11/09 23:34:46 pierre
+ resolving_forward boolean used for references
Revision 1.31 1999/11/09 13:00:38 peter
* define FPC_DELPHI,FPC_OBJFPC,FPC_TP,FPC_GPC
* initial support for ansistring default with modes
Revision 1.30 1999/11/08 16:27:20 pierre
+ Reset AnsiStrings to clean up memory
Revision 1.29 1999/11/06 14:34:20 peter
* truncated log to 20 revs
Revision 1.28 1999/11/04 10:55:31 peter
* TSearchPathList for the string type of the searchpaths, which is
ansistring under FPC/Delphi
Revision 1.27 1999/10/26 12:30:41 peter
* const parameter is now checked
* better and generic check if a node can be used for assigning
* export fixes
* procvar equal works now (it never had worked at least from 0.99.8)
* defcoll changed to linkedlist with pparaitem so it can easily be
walked both directions
Revision 1.26 1999/10/21 14:29:34 peter
* redesigned linker object
+ library support for linux (only procedures can be exported)
Revision 1.25 1999/09/10 18:48:02 florian
* some bug fixes (e.g. must_be_valid and procinfo.funcret_is_valid)

* fix for DLL relocation problems
* external bss vars had wrong stabs for pecoff
