* 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.
