Re: Can not build gzip-1.4: bugs around match.S

[Petr Pisar]

I wrote a patch that allows me to compile gzip-1.4.

But I'm not sure whether the assembler check in configure works correctly.
I think the assembler implementation is not used anymore and it's triggered on
my system just because config.h exists in /usr/include. (On other systems this
check failes because lib/config.h does not exist at configure time.
