Juergen,
I know C and C++ that use threads ....pthread.h requires posix(on). I know
there are other functions that require it

One restriction that I found is that POSIX(ON) can one enclave in an LE
"nested enclave" environment can have POSIX(ON) active. I don't really know
what a "nested enclave" is or why you'd use one.

In LE, an enclave is a mainline and it's subroutines. Certain program
functions create a nested enclave: the invoking enclave is suspended
until the invoked enclave terminates. In particular, I seem to recall
that
* EXEC CICS LINK and EXEC CICS XCTL
* Assembler LINK
* C system() function
* PL/I fetch and call to a fetchable main PL/I procedure
all create nested enclaves; the invoked program must be a 'main' (in
the LE sense) and not a subroutine.
