Pascal,
I was reusing an explanation paragraph and an example that came from an old discussion with Chucky. The explanation and the paragraph ultimately, I understand, came from you, which is why I left the mention of your name.
I'm always happy to see my name when people are handing out credit :-)
There was indeed no question in my message. A summary for it would just be "Hey, look, this relatively obscure rule in the C standard does really matter".
Rules that prevent people doing things are less obscure than those that allow you to do things because nobody ever talks about the latter. -- Derek M. Jones tel: +44 (0) 1252 520 667 Knowledge Software Ltd blog:shape-of-code.coding-guidelines.com Source code analysis http://www.knosof.co.uk
