84 * NOTE - if GS_FAKE_MAIN (above) is set to 1, this hack applies - and you

91 * The Foundation classe NSProcessInfo need access to the argc, argv,
92 * and env variables of the main() function. The purpose of this (ugly hack)
93 * definition is to give the gstep-base library the opportunity to implement
94 * its own main function with private access to the global vars. The private
95 * main() implementation (in NSProcessInfo.m) will then call the user defined
96 * gnustep_base_user_main() function.

102 **
103 ** NOTE! This is very dirty and dangerous trick. I spend several hours
104 ** on thinking and man pages browsing, but couldn't find better solution.
105 ** I know that I will spend 666 years in the Computer Hell for writing
106 ** this hack, and the master devil (Bully Boy) will send me to write
107 ** Windowz software.
108 ** BTW, for writing this hack I got personal congratulations from Dennis
109 ** Ritchie and Bjarne Stroustrup sent me a bunch of flowers and asked me
110 ** to participate in the standardization committee for C-- v.6.0 as
111 ** responsible for the new Tab-Overriding-Operator and Scope-Sensitive-
112 ** Comments ... but this makes my situation even worse ;-)
113 ** - Georg
114 *
115 * On some systems, there are other relatively clean workarounds, if this
116 * applies to the system you are running on, your configuration script
117 * should have set GS_FAKE_MAIN to zero, so that this define hack will
118 * not be used.
