Re: Subject: Kernel bugs that trip expect (Was: Re: 2 new regression on darwin6.1)

If you have expect patches have you submitted them back to the expect 
maintainers?  This is now hosted at SourceForge.

This won't help gcc & gdb, because they use a weird hacked version of 
expect - the current expect won't run the testsuite correctly.  But if 
you have found some Linux bug, you should submit a patch to the 
SourceForge patch tracker...
