You might want to try compiling it with c89 inside the Posix Shell. This will
use the Posix library (which is different from the LIBC@ libraries in LIB.SYS)
if the Posix Developer Kit is installed properly.

I suspect chdir() and mkdir() being part of the Posix functions and thus not
available from the C library that your CCXL compile/link command was using.

Hope this helps.

manuals)
