/******************************************************************************
*
* fd2inline
*
* Should be able to parse CBM fd files and generate vanilla inline calls
* for gcc. Works as a filter.
*
* by Wolfgang Baron, all rights reserved.
*
* improved, updated, simply made workable by Rainer F. Trunz 1/95
*
* Completely reworked Version, cleaned up and removed a whole lot of bugs
* found by Kamil Iskra.
*
* Expect miracles now (hopefully...). Ok, I am just kidding :)
*
* Version 0.99a by Rainer F. Trunz 6/95
*
* Version 0.99b and later by Kamil Iskra.
*
* Version 1.3x by Martin Blom
* See fd2inline.guide/fd2inline.info for details.
*
* version 1.39 by AROS development team
