Arch Linux

Description:

I found a bug which makes the Arch ABS package for drscheme fail to compile; however, this bug has nothing to do with drscheme itself. Drscheme happens to have a subdirectory called "gcc", and apparently, this makes the Arch version of gcc very unhappy. Here is a very simple example. Take this file, called "hello.c":

#include <stdio.h>

int main(void)
{
printf("hello, world!\n");
return 0;
}

Then make a subdirectory in the same directory where "hello.c" lives, and call it "gcc":

% mkdir gcc

Then try to compile "hello.c":

% gcc hello.c

You get this output:

> gcc hello.c

What's worse is that the compile goes smoothly if you give an explicit path for gcc:

% /usr/bin/gcc hello.c
% a.out
hello, world!

However, the gcc in the path is definitely /usr/bin/gcc:

% which gcc
/usr/bin/gcc

This is driving me crazy, so I hope you can figure out what's going on.

Additional info:
* package version(s)
gcc 4.3.2
* config and/or log files etc.
