Q64033: D2030 Caused by Undefined Identifier in Parameter List

Article: Q64033
Product(s): See article
Version(s): 6.00
Operating System(s): OS/2
Keyword(s): ENDUSER | buglist6.00 | mspl13_c
Last Modified: 31-AUG-1990

Using an undefined symbol in a function or function prototype's
parameter list can cause the internal compiler error D2030 in
Microsoft C version 6.00 under OS/2.

The code below produces the following errors under default
optimizations with Microsoft C version 6.00 under OS/2.

   error C2065: 'maxfields' : undefined
   error C2057: expected constant expression

   Command line error D2030 : INTERNAL COMPILER ERROR in 'P1'
                   Contact Microsoft Product Support Services

If output is redirected to a file or a pseudofile, such as the compile
window in the Programmer's WorkBench (PWB), only the internal compiler error
will be displayed.

Microsoft has confirmed this to be a problem with C version 6.00. We
are researching this problem and will post new information here as it
becomes available.

Sample Code
-----------

void foo (char retstring[maxfields]);

void main(void){}
