 * NOTE - if GS_FAKE_MAIN (above) is set to 1, this hack applies - and you
 * must make sure that this file is included in any file that implements

 * You should NOT include this file in a program that does not link with
 * the base library.
 * This file is included automatically in NSObject.h and Foundation.h
 *
 * The Foundation classe NSProcessInfo need access to the argc, argv,
 * and env variables of the main() function. The purpose of this (ugly hack)
 * definition is to give the gstep-base library the opportunity to implement
 * its own main function with private access to the global vars. The private
 * main() implementation (in NSProcessInfo.m) will then call the user defined
 * gnustep_base_user_main() function.

 **  NOTE! This is very dirty and dangerous trick. I spend several hours
 ** on thinking and man pages browsing, but couldn't find better solution.
 ** I know that I will spend 666 years in the Computer Hell for writing
 ** this hack, and the master devil (Bully Boy) will send me to write
 ** Windowz software.
 ** BTW, for writing this hack I got personal congratulations from Dennis
 ** Ritchie and Bjarne Stroustrup sent me a bunch of flowers and asked me
 ** to participate in the standardization committee for C-- v.6.0 as
 ** responsible for the new Tab-Overriding-Operator and Scope-Sensitive-
 ** Comments ... but this makes my situation even worse ;-)

 *
 * On some systems, there are other relatively clean workarounds, if this
 * applies to the system you are running on, your configuration script
 * should have set GS_FAKE_MAIN to zero, so that this define hack will
 * not be used.
