Some.  I'd recommend using Apache 2.0 for this case because httpd-2.0 
is already using threads (and sets up the compiler flags accordingly).
I have a feeling that he is compiling Apache 1.3/mod_webapp/apr 
without _REENTRANT defined at compile-time, so bad things will happen 
on Solaris when you try to create a thread at run-time.

Also, remember that there are two versions of the Solaris threading 
libraries (apr would use pthread and his ORB would use thread).
However, the man pages say that they *should* be compatible even in
the same process.  They even have an example in the man pages...

This leads me to believe that _REENTRANT isn't defined correctly at 
compile-time.  -- justin
