# The MPE POSIX libc archive library contains rand(), but this function has
# been omitted from the libc shared library on the mistaken assumption that
# the rand() function in the kernel library /SYS/PUB/XL could be used instead.
# However, rand() in /SYS/PUB/XL is a Fortran function with different semantics
# from the C version that we expect.
# So in order to get the correct rand() function and to make it available to
# the dynamically loaded perl extensions, we will build our own mini rand()
# shared library and add this to the perl NMPRG's XL list.
