Description Andrew Niefer

void isTrue( int field, int bit ){
   return ( (field) & (bit) );
}

The (field) & (bit) is being parsed as a cast expression instead of as a binary
expression.

This was found in the DOTL project (http://sourceforge.net/projects/dotl/) where
it takes the form of a macro 
#define IS_SET(flag,bit)  ((flag) & (bit))

This is an ambiguity. 
If field was a type rather than an parm passed in, it could even be valid.

Future means you commit to fix it in the Future. Inboxes can't make committments. Moving to '--'.
