Michael Kerrisk be095d1e02 tfix 2008-06-11 06:24:39 +00:00
Michael Kerrisk 7e8c232152 Remove statement that LSB deprecates the functions 
"endmntent(), setmntent() [sic] and setmntent()".
This doesn't seem to be true (I can't find mention of
deprecation in any of the LSB specs).  Rather, LSB simply
doesn't specify these functions.  (LSB 1.3 had a spec of
setmntent(), but not getmntent() or endmntent(), and noted
that having a spec of setmntent() was of little use without
also having a spec of getmntent().)
