- Since version 1.3.3, FLTK now checks for compiler support of -fvisibility

and -fvisibility-inlines-hidden and uses it if available to reduce shared
  library size.  Unfortunately, this hides Fl_XFont_On_Demand::value, which
  in turn causes undefined reference errors during linking.  Fix by marking
  Fl_XFont_On_Demand class as FL_EXPORT for the time being (Gentoo Linux is
  doing the same)
- Do not strip libraries for now: FLTK uses the same command for installing
  both dynamic and static libraries, but "fltk-config(1) --compile" prefers
  static, which breaks programs like `graphics/iccexamin' (threading test)
- Pull another patch from Gentoo to fix segmentation fault in vncview(1) of
  port `net/tigervnc' (Gentoo bug #529856 by Maxim Britov)
- Do not leak non-existent (build-time only) -Lfoo references in LDFLAGS as
  it can potentially lead to various sporadic bugs in programs which obtain
  these flags through fltk-config(1).  To prevent build-time conflicts that
  this gimmick was originally used for, we change shared linking command of
  fluid(1) accordingly

Since these are one-line changes likely to be merged upstream sooner rather
than later, perform them with sed(1) instead of trivial patches.
