Update of /cvsroot/libsysio/libsysio/src
In directory sc8-pr-cvs1:/tmp/cvs-serv11329/src
Modified Files:
Tag: RedStorm
chdir.c fcntl.c getdirentries.c ioctl.c lseek.c open.c read.c
stat64.c truncate.c write.c
Log Message:
Incorporating the head dragged in a whole bunch of symbols. Mostly, improperly
defined. They were functions instead of aliases :-( Fixed that...
Along the way, base everything around __USE_LARGEFILE64 from the glibc
headers when trying to get the xxxx64() entry-points. If this isn't
being compiled under glibc then __USE_LARGEFILE64 is defined to be 0. Which
means that the internal offset, stat, statvfs, etc types all become the
defaults from the system and everything is considered to be "natural".
This is a very intrusive change. Everybody should retest.
