Question for removing trailing whitespaces (not vertical tab) from source

[Kai Tietz]

Hello,

I want to remove some trailing whitespaces from gcc source as coding style 
demands. Also I wrote, while doing a small tool for that, a feature to 
replace horiz. tabs by spaces. But the question is by which width should 
be used ? The gcc source was written by using different tab widths :(

May somebody can give me an advice.

Regards,
 i.A. Kai Tietz
