Re: reiserfs on 2.4.1,2.4.2-pre (with null bytes patch) breaks mozilla compile

[David <david@kalifornia.com>]

I can say "me too" for this.  I thought it was perhaps glibc or binutils 
tho.  I only have reiserfs systems now so I don't have a basis for 
comparison.

However I -can- say that I didn't experience this until I put glibc 
2.2.1 on my systems.  I do use an "approved" gcc, stock 2.95.2.

I wouldn't be so quick to pin it on reiserfs.
