FIX: Errors C2065/C2064 When Function L is Called with Macro

ID: Q152016

The information in this article applies to:

Microsoft Visual C++ 32-bit Edition, versions 4.1, 4.2

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.
