/*
|
||||
* 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.
