Title: Detailed 2.2.0 Todo

OldNewLine
1+This todo is for people working on fpc to write down what they want to do till 2.2.0 is released. It's not a wishlist what shall be done. Feature requests etc. should be added to mantis.
2+
3+### General
4+
5+- Document changes potentially affecting currently working code to [[User Changes 2.2.0]] (all)
6+ - Document regcal stack parameter order change
7+ - Document val change regarding the handling of \#0
8+- Fix bugs with [target 2.2.0](http://www.freepascal.org/mantis/view_all_set.php?type=3&source_query_id=623)
9+
10+### Compiler
11+
12+- ~~packages (Florian/Peter)~~ (2.4.0)
13+- ~~[[Module handling rewrite]] (Peter/Florian)~~ (2.4.0)
14+- ~~Crosscompiling to Mac OS X~~ (Marco, been done, but not end user ready -\>2.4.0)
15+- ~~rewrite assigning of automated types like variants and widestrings (Florian)~~
16+- ~~complete unique type support (Florian)~~
17+- dispinterfaces (Florian)
18+- improve HTML rendering of IDE (Florian/Tomas(?))
19+- ~~Internal linker for ELF platforms?~~ (2.4.0)
20+- ~~better string append support (Peter)~~
21+- ~~Use Sysutils (Peter)~~
22+- ~~Directory caching (Peter)~~
23+- ~~All path/filename handling in the compiler ansistring. (Thomas)~~
24+- generics support (Florian)
25+- ~~PIC support for Darwin/ppc and Darwin/i386 and compile rtl, packages and fcl with PIC support because non-PIC dynamic libraries are unsupported (although they work in simple situations) (Jonas)~~
26+- Fix all testsuite failures which are in 2.1.x but not in 2.0.x (all)
27+- bug fixing (all)
28+ - ~~Delphi incompatibility regarding register calling convention (push order of stack based arguments) (Florian)~~
29+ - ~~fix bugs in *nix tthread.inc's (joining detached threads, possibly some more dataraces) (Jonas)~~
30+- ~~Binary writer generates incorrect debug info, for example enums do not show. (Peter)~~
31+- Ansistrings/widestrings should show in gdb as string, not address. We can achieve this by emitting debug information for zero terminated strings.
32+- Fix -pg gprof support.
33+
34+### Packaging
35+
36+- Use fpmake for building (Michael/Peter)
37+- Use fppkg for package repository (Michael/Peter)
