Coding convention: use of `!x' vs. `! x'

[Tim Josling]

Before adding new standards I think it would be better to have
the existing standards followed more closely eg comments and
meaningful variable names. At present these are the major hurdles
in front of anyone wanting to help with GCC. In particular the
configure/make files are a major 'swamp of no return'.

Maybe it is deliberable to stop people who don't know what they
are doing from getting involved. 

Are there any programs to test for FSF standards compliance,
realizing that full checking is not possible, you could check
quite a lot.
