An MS-Windows executable, (such as groff.exe), cannot (easily) spawn a
Bourne shell script, (because there is no native interpreter for it);
the same is true of perl. Of course, it is possible to spawn such
scripts *indirectly*, (by explicitly spawning a suitable interpreter),
but, depending on which specific interpreter implementation happens to
be installed, (there is no standard), YMMV.

Was that under MS-Windows natively? Or under Cygwin?

Possibly, but to invoke it from within an MS-Windows executable is
messy, and potentially unreliable.

A good starting point may be to implement a C/C++ library function, to
extract the MediaBox properties; that would open the gate to a possible
pdfbb request, which gtroff.exe could process internally.
