78 * GCI_STACK_ELEMENT sets integral type of a stack element. This is typically
81 #define GCI_STACK_ELEMENT unsigned
84 * GCI_LITTLE_ENDIAN must be set to 1 or 0 depending on whether little endian
85 * or big endian is the machine's representation.
86 * In doubt, select 1 for Intel compatibles and 0 for others.

97 * GCI_ARGS shall be the maximum number of GCI_STACK_ELEMENTs which shall
98 * be passed on the stack. This is usually the base type of maximum width
99 * (e.g. long long or long double) / sizeof(unsigned) * GCI_REXX_ARGS.
100 * But you can't use sizeof(), therefore you have to compute it by hand.
101 * 4 * GCI_REXX_ARGS is an upper maximum for all useful systems I can imagine.
103 #define GCI_ARGS 64 /* 16 full sized arguments */
106 * GCI_PASSARGS is a macro which enumerates GCI_ARGS args of an array which
107 * is passed to the macro. I don't know a good ANSI macro for this purpose.
108 * Feel free to provide it!
