Correct

What versions of autoconf and automake are you using? These look like
errors from an old version of automake. Specifically, the
AM_MAINTAINER_MODE macro only got it's (optional) argument in automake
1.10a
(http://www.mail-archive.com/aut...@gn.../msg01208.html) so
any older automake won't work. Shipping an updated maintainer.m4 might
help, but I'm inclined to regard automake-1.10 as the minimum for
building Audacity seeing as 1.11 is out.

Am I correct that you are currently trying just to rebuild portsmf's
configure and haven't yet tried to do anything to portmidi?

portsmf should find the copy of AX_CFLAGS_STRICT_PROTOTYPES declared in
lib-src/portsmf/autotools/m4/ax_cflags_strict_prototypes.m4 because
Makefile.am contains
ACLOCAL_AMFLAGS = -I autotools/m4
which tells the aclocal run (which collects macros from all over the
place and places them in lib-src/portsmf/aclocal.m4) to check in the
given directory, i.e. lib-src/portsmf/autotools/m4/

This makes me suspect that your version of aclocal (which is part of the
automake package) is too old and at fault. I'm not quite sure why this
would be, because Fedora 11 got an update to aclocal 1.11.1 (what I'm
using) as a security fix before it reached end of support (you do know
that fedora are ignoring anything before fedora 12 now that 13 is out
and 14 nearly here?)

It's not at the moment because I have more pressing autotools issues
(the Ubuntu build issue in portaudio), which make anything that isn't on
the beta/stable release path fairly low priority for me.
