Re: Fixes to make compile under OpenServer 5 (ITS#972)

Dear Kurt,

Thank you for the time you spent looking over my correction.  Here is the
additional information you requested:

Thank you.

This variable is no longer defined in any location on the SCO platform.  It
is replaced by
a call to the fpathconf() or pathconf() function, where the first argument
is a stream or file
path name respectivly pointing to a directory and the second argument is the
value PATH_MAX.
As different file system on the SCO platform may have different values, the
result is dependant
upon the file system on which the directory resides.  As most uses in
OpenLDAP of the MAXPATHLEN
are to allocate storage during compile time, I had to work out a different
solution.  According to my research, the value 1024 is the highest value
that any file system currently supported on SCO returns as MAXPATHLEN.
Therefore the solutions that I applied to my copy.  You are welcome to it.
However,
if not, it is also OK.

I agree, but as I stated, I don't know how to change configure.  There are
two choices
here: You can do it, you can direct me to where I can get the info how and I
can propose
the change.
