The build stops when trying to link against the icu libraries. According to the dcmtk documentation it should be possible to either use libiconv, icu or iconv from the standard library. So forcing icu does not seem to be a terribly good idea, since icu-64 now went stable.
Sorry, I was too quick. The error is not caused by icu but stricter checking by gcc-9. Clang-8.0 also fails. The offending code is in line 57 of file ofstd/include/dcmtk/ofstd/variadic/helpers.h So the title should be sci-libs/dcmtk-3.6.3 fails to build with gcc-9.1.0.
Without fixing the code itself, the build succeeds when adding "-Wno-error=narrowing" to CXXFLAGS.
