Re: (ITS#7529) mdb.c missing #if MDB_DEBUG at line 3514
Thanks for the follow up Howard. I'm busy cranking out a number of
dependent packages to compile some software, OpenLDAP being one of
many. We have an aversion to the use of GCC here so situations like
this compilation fail are somewhat common. It's nice though when code
is kept simple and portable as it makes life easier.
I don't normally spend much time debugging code and shipping fixes in
a nice box with a pretty bow on it, I've just cut and pasted the two
lines I used to allow compilation, part of the compile recipe used to
crank out this 2.4.33 release.
Hopefully that's enough to update your git archives.
