gnulib builds the module 'getdtablesize' because it's a glibc function:
https://www.gnu.org/software/gnulib/manual/html_node/getdtablesize.html

Are you saying that OpenVMS already has the function and that
m4/getdtablesize.m4 guesses wrong about its existence?

Sure, no one expects to be able to change the number of available
file descriptors of a running process.

Perfect: you already know how to implement the gnulib replacement for
getdtablesize() on OpenVMS.
