New Revision: 317289
URL: https://svnweb.freebsd.org/changeset/base/317289

Log:
  libgeom(3): note that stdio.h is required when referencing gctl_dump(3)
  
  gctl_dump(3) is only exposed when stdio.h is #include'd first, per its
  addition in r112510. The reasoning noted for the conditional "exposure"
  of the function was to "limit #include pollution".
  
  This addresses an issue I found with the documentation when looking at
  bug 218809, which in turn addresses a -Wimplicit-function-declaration
  compiler warning in `tools/regression/geom_gpt/test.c` (it uses
  gctl_dump(3)).
