You are, of course, welcomed to add a subcategory for Digital UNIX in the
platform hints section of the faq-o-matic and then add your 'new answer.'

Where did it find the incompatible pthread_create() ?

BTW, thank you for your work on this project.  Its exciting and a
wonderful service to the community.

I didn't realize you allowed offsite people to modify the faq-o-matic,
although a second look shows this to be true.  

I also realize that this answer looks a lot like some of the other answers
for other OS's regarding pthreads, however it is slightly different and
took a little digging through the man pages on DU.  If this had been in
there, it would have saved me some trouble right off the bat.

Here is the tail of the config.log:

Hi Ashley
Here are my config setting for DU 4.0D for openldap-1.1.3

setenv CC cc
setenv CFLAGS "-O4 -std"
setenv CPPFLAGS "-I/usr/local/include"
setenv LDFLAGS "-L/usr/local/lib"
setenv LIBS "-lpthread -lpthreads"

./configure --prefix=/usr/local/ldap --enable-slurpd --enable-shared\
    --enable-wrappers --with-threads \
    --with-ldbm-api=gdbm

moved from Incoming to Software Bugs

I've made some changes that should resolve pthread detections issues
on Digital Unix 4.0.

In the meantime, I suggest (if using the vendor supplied compiler)
	CFLAGS=-pthread; export CFLAGS
	./configure --with-threads=posix

If using something else (like gcc):
	CFLAGS=; export CFLAGS
	CPPFLAGS=-D_REENTRANT; export CPPFLAGS
	LIBS="-lpthread -lmach -lexc"; export LIBS
	./configure --with-threads=posix

If this doesn't work, try without the -lmach library.

I do NOT recommend using "-threads" nor "-lpthreads" as this will cause
older posix routines to be included.  (In fact, this is why the test
failed).

Note: this will build the complete system with threads (instead of just
the threaded components).

If you are using the vendor supplied compiler.
