Thanks, Abigail; that is very helpful.
After fixing minor syntax errors, I get:

C:\USR\perl>perl -MConfig -e "print $Config::Config {randfunc}"
rand
C:\USR\perl>perl -MConfig -e "print $Config::Config {randbits}"

Most probably, Abigail meant

perl -V:"randfunc|randbits"

One can do

perl -V:".*rand.*"

but it also will get some "detected pre-build" stuff which is not
actually used by perl; so it is better to see "randfunc|randbits"
first.

Hope this helps,
Ilya
