1.5.16 build issues on BSD

[Chris G <cl@xxxxxxxx>]

I'm trying to build mutt 1.5.16 on a BSD system (it's not mine, it's my hosting 
provider,
Gradwell.Net).

uname -a gives:-

    FreeBSD newred.gradwell.net 4.8-STABLE FreeBSD 4.8-STABLE #1


./configure seems to work OK (using --prefix=$HOME) but I needed a specific
--with-homespool as well.

However although it compiles (with *lots* of warnings about things that
ANSI C doesn't support) it fails to link with the following errors:-

    pattern.o: In function `mutt_which_case':
    /home/isbd/build/mutt-1.5.16/pattern.c:150: undefined reference to 
`iswalpha'
    /home/isbd/build/mutt-1.5.16/pattern.c:150: undefined reference to 
`iswupper'
    *** Error code 1

Can anyone suggest how to get around this problem, don't say upgrade the OS as
I said it's not mine so that's not a possibility.  I either need to provide the
missing functions somehow or tell mutt not to use them.
