[fpc-pascal] Pascal grammar for FPC.

[Pascal]

Hello.

In order to get translations from FPC to Ada language, I have updated  
P2Ada translator http://sourceforge.net/projects/p2ada.
I add a new ObjP2Ada branch.

The grammar is based on:
reference guide for Free Pascal (FPC), version 2.2.4, March 2009
programmer's guide Turbo Pascal (TP), version 7.0, 1992
/user manual Think Pascal (THP), version 4.0, 1990
Code Warrior Pascal (CWP) language reference manual, version 11, 1998
Delphi Object Pascal Language Guide, version 7, 2002

I made a specific version of grammar with only syntax elements http:// 
blady.pagesperso-orange.fr/telechargements/p2ada/fpc-nov09.y
This file is yacc compatible.

It would be a great help if someone can check it versus FPC.
In the other hand, it may helps FPC developers to have a grammar  
summary for documentation.

Thanks, Pascal.
