NATURAL v6 (6.3) I think
NATURAL calling a C program under Solaris is working. NATURAL calling same C program under Linux gets a NAT0920.
Tried with the ncuxinit.c and jumptab.c from Solaris. Also changed jumptab.c to better match the template on Linux.
ncuxinit, jumptab, C program are compiled / linked into natuex.so.
NATUSER is exported with the correct path to natuex.so.
Error message does not include any return code.
