Symptoms
When compiling the source below using precompiled headers, you may get thefollowing error from the C/C++ compiler for MS-DOS under Windows:
error C2006: #include expected a filename, found 'identifier'
or the following error from the C/C++ compiler for MS-DOS under Windows NT:
fatal error C1001: internal compiler error
(compiler file 'msc1.cpp', line 585)
or the following errors when compiling with Microsoft Visual C++, 32-bitEdition, versions 1.0 and 2.0:
error C2006: #include expected a filename, found 'identifier'
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 602)

Please choose the Technical Support command on the Visual Workbench Help menu, or open the Technical Support help file for more information
or the following errors when compiling with Microsoft Visual C++, 32-bitEdition, version 4.0,
error C2006: #include expected a filename, found 'identifier'
fatal error C1903: unable to recover from previous error(s); stopping execution
Cause
The problem is in using a defined constant to specify an includefile in the #include directive. The directive is being processedbefore the macro is completely expanded, resulting in the error.
More information
The following sample code can be used to demonstrate the problem.

Sample Code

/* Compile options needed: /Yu"stop.h" * Previously created with /Yc"stop.h" */ 				

FIRST.H

#define SecondH "Second.H"				

SECOND.H

#define SOMETHING				

STOP.H

//This file is empty				

TEST.CPP

#include "First.H"#include SecondH#include "stop.h"
