Hi,

   I'm the worst person to comment on this, but ... if __STDC__ means
ANSI/ISO C89/C90/C99, then lacking that, K&R C won't have _Complex
(C99) keyword anyways. So I fail to see the point. As mentioned, DJ
says older compilers aren't worth supporting (e.g. GCC 2.95.3, which
allegedly only had very very minimal C99 support).
