# April 02 2001 - MT : Initial Translation
|
||||
#
|
||||
# May 08 2001 - DL : Added ExternalSym derectives and copyright header
|
||||
#
|
||||
# April 03 2003 - DL : Added jedi-sdl.inc include file to support more
|
||||
# Pascal compilers. Initial support is now included
|
||||
# for GnuPascal, VirtualPascal, TMT and obviously
|
||||
# continue support for Delphi Kylix and FreePascal.
|
||||
#
|
||||
# April 08 2003 - MK : Aka Mr Kroket - Added Better FPC support
|
||||
#
|
||||
# April 24 2003 - DL : under instruction from Alexey Barkovoy, I have added
|
||||
# better TMT Pascal support and under instruction
|
||||
# from Prof. Abimbola Olowofoyeku (The African Chief),
|
||||
# I have added better Gnu Pascal support
|
||||
#
|
||||
# April 30 2003 - DL : under instruction from David Mears AKA
|
||||
# Jason Siletto, I have added FPC Linux support.
|
||||
# This was compiled with fpc 1.1, so remember to set
|
||||
# include file path. ie. -Fi/usr/share/fpcsrc/rtl/*
