ls-mnt-fs.m4

[NightStrike]

I was trying to decipher how configure works at the part where it is
checking to see how to get a list of mounted file systems.  My search
led me to this:

m4/ls-mntd-fs.m4

In that file is the text:

# Replace Autoconf's AC_FUNC_GETMNTENT to work around a bug in Autoconf
# through Autoconf 2.59.  We can remove this once we assume Autoconf 2.60
# or later.


In configure.ac is:

AC_PREREQ(2.61)


Based on the comment, was the stuff in that file removed?  If it was,
where do all of the "getmntent" functions come from?
