* tclUnixPort.h --
*
* This header file handles porting issues that occur because
* of differences between systems. It reads in UNIX-related
* header files and sets up UNIX-related macros for Tcl's UNIX
* core. It should be the only file that contains #ifdefs to
* handle different flavors of UNIX. This file sets up the
* union of all UNIX-related things needed by any of the Tcl
* core files. This file depends on configuration #defines such
* as NO_DIRENT_H that are set up by the "configure" script.
*
* Much of the material in this file was originally contributed
* by Karl Lehenbauer, Mark Diekhans and Peter da Silva.
