This is specific to the aC++ runtime, not the version of the aC++ compiler.
If you link with libpthread.1, you must compile everything with -mt.

Yes.

No.  This application is NOT single-threaded if you link with libpthread.1.
If you don't call pthread_create, you may want to consider stubbing out
libpthread.1, if you can't remove the dependency.

Who is linking in libpthread?
Using chatr(1) on each shlib and the executable.

>Works fine on hpux 11.23 and aCC A.06.10

I'm not sure how?

Did you try compiling everything with -mt?
