wait a moment and calm down. I don't want to mix runtimes, just select a 
compiler. I don't even know how to select a runtime!

I just have David's runtime installed because it is an installed package 
on my FreeBSD system.
The only thing I explicitely do is to select gcc5 as a compiler (always 
installed from ports) and it comes with its own runtime.

David told me once that his runtime is usable with gcc. I hope this 
still holds.


Where do you see that I configure base to use the gcc runtime and mix 
library and headers?

I configure "make" this way:

/configure --with-layout=gnustep --prefix=/ CC=gcc5 CXX=g++5 
LDFLAGS=-Wl,-rpath=/usr/local/lib/gcc5

My intention with this is to select gcc5 and give embed its link path 
with its library if it is needed.

I then configure "base" with just "./configure" nothing else.

I think by having both runtimes available/detected, David's should have 
preference, but I would even be fine using gcc's, but as you say consistent.

I'll test Richard's LDFLAGS and report.
Actually, how do I know which runtime is being used? Run ldd on base's 
library?

E.g. on a similar FreeBSD system but which uses only clang, I see:
libobjc.so.4.6 => /usr/local/lib/libobjc.so.4.6 (0x801df9000)

We shall see what I get when using gcc5 then!
