SYMPTOMS

Compiling a program that calls the function "L" using a macro will cause the following errors:

error C2065: 'x' : undeclared identifier

error C2064: term does not evaluate to a function

where "x" is the last letter of the macro identifier.

CAUSE

In this case, the preprocessor incorrectly generates the letter "x" as the resulting output.

RESOLUTION

Use any other letter after "L" in the macro body.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.

       };
