Hi,

In GNU libffcall, I make use of libtool's '-export-symbols-regex' option.
Since the doc says "This option has no effect on some platforms." I wanted
to know more, in order to judge whether it's worth doing additional measures
for library namespacing.

Here's what I found:
  * It has no effect on static libraries.
  * It has the desired effect on shared libraries on
      - most ELF systems (Linux, FreeBSD, NetBSD, OpenBSD, Solaris 10 and 11,
        Android),
      - macOS,
      - Cygwin,
      - native Windows (mingw, MSVC).
  * It has no effect on AIX and Haiku.

Find attached a doc patch.
