I tested compiled it on OpenBSD sparc, and found a problem while linking 

cc  -Wl,-E       -fgnu-runtime -o obj/autogsdoc \
        ./obj/autogsdoc.obj/autogsdoc.m.o ./obj/autogsdoc.obj/AGSParser.m.o

When I reported some days ago the compilation problem with libicu4c, then my 
tests were made with icu4c-4.4. On OpenBSD sparc, the default compiler is 
gcc-2.95. However, icu4c is weird, that it has to be compiled with 
gcc/g++-3.3.6 from the ports, and therefore it installs libstdc++-3.3.6. The 
library is named libestedc++

To fix the linking problem manually, I added -lestdc++ to the config.mak file.
There probably should be a better way using autoconf/configure to detect which 
is the right lib to link against.
On i386, the problem doesn't exist, there the default compiler is gcc-4.2.1, 
and it took and linked against /usr/lib/libstdc++
