--- Comment #1 from Carlos E <kaploceh at gmail dot com> ---
I haven't had any problems compiling it with Make before, usually it goes into:

 g++  -O3 -pedantic -std=c++2a -g -Wall -Wextra -Wno-unused-parameter
-Wno-sign-compare -Wno-address -Wno-init-list-lifetime -MD -MP -MF <file.d> -c 
-o <file.o> <file.cc>

with the variable CXXFLAGS += -pedantic -std=c++2a -g -Wall -Wextra
-Wno-unused-parameter -Wno-sign-compare -Wno-address from the Makefile


and so on

But this time around, it stops right with the message

 internal compiler error: in tsubst_pack_expansion, at cp/pt.c:12930

It finishes by telling me to 

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

while GNU Make says 

   Once you have a precise problem you can report it in one of two ways.
Either send electronic mail to:

         bug-make@gnu.org

or use our Web-based project management tool, at:

         http://savannah.gnu.org/projects/make/


So I'm reporting it here rather than over there.
