#58469: pdftk @2.02_0+gcc5 calls abort() with symbol
__darwin10_Unwind_FindEnclosingFunction not found on 10.14 (since gcc9
@9.1.0?); pdftk build also broken because gcj-mp-5 (from gcc5 @5.5.0_4)
abort()s in the same way; likely all else built with gcj also affected

--------------------------+------------------------
 Port `pdftk` @2.02_0+gcc5 is broken on macOS 10.14 (and presumably all
 macOS since 10.7). It was built using `gcj-mp-5` from port `gcc5`, and its
 runtime library `libgcj.16.dylib` references a symbol,
 `__darwin10_Unwind_FindEnclosingFunction`, expected to be provided by
 `libgcc_s.1.dylib`.

 Since [https://github.com/macports/macports-
 ports/commit/ac5a416fd8dc537e38f9c55b39e5e9e873c3454d macports-ports
 ac5a416fd8dc], `libgcc_s.1.dylib` is provided by port `libgcc9` @9.1.0 on
 macOS 10.7 and later. GCC 9 no longer offers
 `__darwin10_Unwind_FindEnclosingFunction` in `libgcc_s.1.dylib`. This is a
 change in upstream GCC as of
 [https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=738b5536dcf328b72e92dcf84eaf2d032f22a730
 gcc 738b5536dcf3]. `__darwin10_Unwind_FindEnclosingFunction` is now
 provided by `d10-uwfef.o`. But `gcj-mp-5` from port `gcc5`, which built
 `pdftk`, doesn’t know to look for it.

 In addition, I attempted to build `pdftk` from source:

 {{{
 % sudo port install -s pdftk
 }}}

 But the build fails when `gcj-mp-5` calls `abort()` on failing to resolve
 the same symbol. A snippet from the build log:
