00000 /* The <ansi.h> header attempts to decide whether the compiler has enough
00001 * conformance to Standard C for Minix to take advantage of. If so, the
00002 * symbol _ANSI is defined (as 31415). Otherwise _ANSI is not defined
00003 * here, but it may be defined by applications that want to bend the rules.
00004 * The magic number in the definition is to inhibit unnecessary bending
00005 * of the rules. (For consistency with the new '#ifdef _ANSI" tests in
00006 * the headers, _ANSI should really be defined as nothing, but that would
00007 * break many library routines that use "#if _ANSI".)
00008
00009 * If _ANSI ends up being defined, a macro
00010 *
00011 * _PROTOTYPE(function, params)
00012 *
00013 * is defined. This macro expands in different ways, generating either
00014 * ANSI Standard C prototypes or old-style K&R (Kernighan & Ritchie)
00015 * prototypes, as needed. Finally, some programs use _CONST, _VOIDSTAR etc
00016 * in such a way that they are portable over both ANSI and K&R compilers.
00017 * The appropriate macros are defined here.
