Re: Infinitely long compilation

Hi Bryce,
turned out that the problem was fast to find out.
I do not know, how to make this patch correct in the gcc-way,
but it works for me. The problem is this:

If you have a name foo.bar you replace it by foo@bar,
try that for an identifier and then change the name back to foo.bar.
If it was not an identifier, do the same again....

Perhaps the line
*separator = c;
could simply be left out, but i do not know, whether the original name
will be used later. So i made the changes on a private copy.

Thanks for your help,
Martin.


PS: The patch is against gcc-20020325.
