+# 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.
