iostream.h, line 1: catastrophic error: #error directive:
<iostream.h> is not a Standard header, use <iostream> instead.
Note that when you change this header name, that identifiers such as
"cout" and "endl" will no longer work, as they are in namespace
"std", so use be "std::cout" and "std::endl" respectively.

1 catastrophic error detected in the compilation of "ComeauTest.c".
Compilation terminated.
