I have notified Comeau of the bug. It can be seen just by:

#include <cstdarg>

void test() { std::va_list avar; }

ATEST.CPP(3):
error #276: name followed by "::" must be a class or namespace name
  std::va_list args;
  ^
ATEST.CPP(3):
error #65: expected a ";"
  std::va_list args;
               ^
and just compiling, option -c, with no other options ( vc71 default is 
set ). I have notified Comeau of the problem and am awaiting another 
response from them. Their first response was to say what you did, about 
"compiler magic", but since I did not have a simple test case, I replied 
with the example above.
