SubjectCompile error including asm/uaccess.h
From
Date
    GLIBC VERSION: 2.3.1

HOST MACHINE and OPERATING SYSTEM: i686 Gentoo Linux 1.4.2.9

KERNEL VERSION: 2.4.18

TARGET MACHINE and OPERATING SYSTEM, if different from HOST: Same

COMPILER NAME AND VERSION (AND PATCHLEVEL): g++ 3.2.2

DOES THE PROBLEM AFFECT:
COMPILATION? Yes.
LINKING? No
EXECUTION? No
OTHER (please specify)? No

SYNOPSIS:

Receiving a compiler error when attempting to include asm/uacccess.h

DESCRIPTION:

I am compiling a program that is written in C++ so the g++ compiler is
being used to compile the source. On of the headers of a dependent
library is including asm/uaccess.h. When I attempt to compile this
program I get parse errors.

REPEAT BY:

Here a test programs that I did:

#include <asm/uaccess.h>

int main (){
return 0;
}



SAMPLE FIX/WORKAROUND:

None.
