Fine with me.

Yes, right.

Since you are already pointing out that your sed program is likely unportable,
why not use the classical style with s and t commands instead? It's not much
longer:

/gl_MODULES(/ {
  :a
    s/)/)/
    tb
    N
    ba
  :b
  s,^.*gl_MODULES([[ ]*\([^])]*\).*$,cached_specified_modules="\1",p
}
