Compilation error with gcc 4.0.1 +quick fix

It wouldn't compile as-is.

What I did:
./configure
make

Error:
output.c:26: error: static declaration of ‘output’ follows non-static 
declaration
indent.h:100: error: previous declaration of ‘output’ was here

This was with gcc 4.0.1.

How I fixed it:
#ifndef so 'output' isn't declared in indent.h when output.c includes it.

#define before output.c includes indent.h
#undef after

This is just a quick fix, there is probably a much cleaner way to do it.

Anyway, I'm including diffs of the two files I changed.

Thanks,
David Hill.
