AFAIK this is true.

See GTK - use libtool:

 # libtool option to control which symbols are exported
 # right now, symbols starting with _ are not exported
 LIBTOOL_EXPORT_OPTIONS='-export-symbols-regex "^[[^_]].*"'
 AC_SUBST(LIBTOOL_EXPORT_OPTIONS)

We make private symbols start with _, but if you didn't want to do
that you can also have a file where you make a list of private
symbols. libtool just uses the regexp to generate the file.
