/* OS specific routines for AMIGA platform.

* John Bush <John.Bush@east.sun.com> BIX: jbush
* Paul Kienitz <kie@pacbell.net>
*
* History:
*
* Date DoBee Comments
* ------- -------- -----------------------------------------------
* 21Jan93 JBush Original coding.
* Incorporated filedate.c (existing routine).
*
* 31Jan93 JBush Made filedate.c include unconditional.
*
* 18Jul93 PaulK Moved Aztec _abort() here from stat.c because we
* can't share the same one between Zip and UnZip.
* Added close_leftover_open_dirs() call to it.
*
* 17Apr95 PaulK Added Amiga internal version string so that
* installer programs can compare the version being
* installed to see if the copy the user already has
* is older or newer. Added Prestart_Hook to support
* debug tracing in deflate.a.
*
* 6May95 PaulK Added GetComment() for filenote support.
*
* 12Nov95 PaulK Added #define ZIP in front of filedate.c, for
* new options in there; removed declare of set_con()
* since echon() no longer expands to it (or anything).
*
* 12Feb96 PaulK Removed call of echon() entirely.
*
* 12Jul97 PaulK Made both Aztec and SAS define USE_TIME_LIB for filedate.c
*
* 26Aug97 PaulK Added ClearIOErr_exit()
*
* 2Jan98 HWalt Adapted for SAS/C using stat.c replacement functions
*
* 6Jun00 PaulK Removed references to time_lib, since new filedate.c
* supercedes it
