Re: error: 'char16_t' does not name a type; did you mean 'wchar_t'? (Was: Bug#899129: prime-phylo: FTBFS: cd obj-x86_64-linux-gnu && make -j8 -Oline returned exit code 2)

Otherwise you can just define it. See e.g.
https://cgit.freedesktop.org/libreoffice/core/diff/configure.ac?id=fabad007c60958f2ff87e8f636ff6a798ad1f963
+if test "$ICU_MAJOR" -ge "59"; then
+ # As of ICU 59 it defaults to typedef char16_t UChar; which is
available
+ # with -std=c++11 but not all external libraries can be built with
that,
+ # for those use a bit-compatible typedef uint16_t UChar; see
+ # icu/source/common/unicode/umachine.h
+ ICU_UCHAR_TYPE="-DUCHAR_TYPE=uint16_t"
+else
+ ICU_UCHAR_TYPE=""
+fi
(but yes, projects using -std=c++11 don't need it.)
