[ft-devel] improve symbol export on non-Windows platforms

[Werner LEMBERG]

Folks,


I want to apply the following patch


--- a/builds/unix/unix-cc.in
+++ b/builds/unix/unix-cc.in
@@ -109,6 +109,6 @@
 LINK_LIBRARY = $(LIBTOOL) --mode=link $(CCraw) -o $@ $(OBJECTS_LIST) \
                           -rpath $(libdir) -version-info $(version_info) \

 # EOF


This was commented about 10 years ago – I think the reason then to
disable libtool's `-export-symbols' option was to give some badly
programmed applications access to internal FreeType functions.

I believe that we should no longer take care of such programs; the
number of symbols exported should be rather restricted as much as
possible (see list of skipped symbols below).

Any objections?
