[Samba] Compile error in statvfs.c in samba 3.0.22

[sboydlns at gmail.com]

I am trying to build samba 3.0.22 on an older Slackware system. 

gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) 

The error I'm getting is 

smbd/statvfs.c: In function `linux_statvfs': smbd/statvfs.c:40:
incompatible types in assignment 
Anyone have any clues?
