Does this app use some sort of autoconfigure script to determine what OS
functionality exists?  If so, double-check to make sure accurate answers were
obtained.  It is common for these scripts to come up with "false positives" on
MPE, which then go on to produce unresolved externals.

If the autoconfigure script was accurate, and any manual modifications are
accurate, you must scan the source for these unresolved externals to see if any
alternative solutions are provided.  Sometimes you just have to look at the
source to find out the correct build options.

Things like strdup, fsync, fchown, ftruncate all have MPE implementations
embedded in various ports that have been done in the past.

Some things like chroot cannot be truly implemented, so you either need to be
VERY creative with a "good enough" implementation, or be willing to live
without the functionality.

I've never seen the obstack stuff or the stpcpy/mempcpy variants before.
