autoconf incorrectly(?) reports that g++ can't build shared library on OpenBSD

[Mike]

I have troubles with configuring some applications with their configure
script (for ex. verlihub-0.9.8d_RC2, autoconf-2.59) on OpenBSD-4.3,4.5,4.6
(gcc-3.3.5propolice, gmake-3.81):

bash-4.0# ./configure 
.. 
configure: creating libtool 
appending configuration tag "CXX" to libtool 
checking for ld used by g++... /usr/bin/ld 
checking if the linker (/usr/bin/ld) is GNU ld... yes 
checking whether the g++ linker (/usr/bin/ld) supports shared libraries... no 
checking for g++ option to produce PIC... -fPIC 
checking if g++ PIC flag -fPIC works... yes 
checking if g++ supports -c -o file.o... yes 
checking whether the g++ linker (/usr/bin/ld) supports shared libraries... no 
checking dynamic linker characteristics... openbsd4.6 ld.so 
.. 
 
Is it because OpenBSD restrictions or autoconf bug ? 
Applying autoconf-2.62, 2.64 has the same result. 
Reading autoconf script I can't find proper cheking for openbsd. 

I've solved this problem by following patch:

I know, this is not good way (need to check versions etc), but after
building this app with my patch it's working good. 
After trying to build midnight commander on MacOS-10.5 (darwin-xx),
I think that gnu autoconf is full of bugs.
