/*====================================================================
_MSC_VER Microsoft C 6.0 and later
_QC Microsoft Quick C 2.51 and later
__TURBOC__ Borland Turbo C, Turbo C++ and BC++
__BORLANDC__ Borland C++
__ZTC__ Zortech C and C++
__SC__ Symantec C++
__WATCOMC__ WATCOM C
__POWERC Mix Power C
__GNUC__ Gnu C
__EMX__ Emx Gnu C
Revised:
Original Scott Ladd Now obsolete
14-Sep-93 Fred Cole Moved MK_FP() macro to end of file to avoid
redefinition error when dos.h gets included
at the in/outport definitions for __TURBOC__
15-Sep-93 Thad Smith Add conditional code for TC 2.01
Fix findfirst/findnext support for ZTC 3.0
15-Oct-93 Bob Stout Revise find first/next support
02-Dec-93 David Nugent Additions for findfirst/findnext support for
MSC6 (& 7) for OS/2
Added FIND_END macro for use under OS/2 to
be nice about closing the directory handle
DOSFileData members should be accessed via
the new ff_*() macros for portability
Note: use -DOS2 when compiling under OS/2
03-Apr-94 Bob Stout Add Power C support, FAR
19-Aug-95 Bob Stout Add NEAR, PASCAL, CDECL, and portable attributes
06-Sep-95 Phi Nguyen Add DOSFileTime, DOSFileDate, & supporting macros
Bob Stout (ff_yr/mo/day(), ff_hr/min/tsec())
08-Sep-95 Bob Nelson Add __GNUCC__ and PAK macro
21-Sep-95 Bob Stout Renamed to PC-PORT.H, revised directory stuff
25-Sep-95 Bob Stout Split out EXTKWORD.H
26-Sep-95 Jerry Coffin Added Win32 support.
21-Oct-95 Bob Stout Resolve struct dirent incompatibilities,
move port I/O macros to PCHWIO.H,
move MK_FP() cover to SNIPTYPE.H,
rename to DIRPORT.H(!!!)
15-May-96 David Nugent Added 32-bit OS/2 support (Watcom/emx)
04-Jul-96 Bob Stout Fixed attribute redefinition problems w/ TC 3.x
28-Jul-96 Bob Stout Fixed error in definition of ff_sec() in DOS
20-Aug-96 Bob Stout Eliminate Win32 conflicts
