Here is the report I promised. I followed the path below:
1. Got source from CRAN.
2. Read instructions under "Download R for (Mac) OS X"
(shouldn't that read "Download R for macOS" nowadays?). Especially the
note Important: "If you wish to compile R packages ..., see the tools
directory."
3. In the tools directory: Download and install clang-7.0.0.pkg (I see
now that I should have chosen clang-8.0.0 for R 3.7.0, which is
R-devel?). Also download and install gfortran-6.1.pkg (It says: "To be
used with El Capitan builds of R.", which worried me a little, since I
am on High Sierra, but there were no alternatives.)
With this setup I got my first reported error. Thanks to Peter, I went
on to
https://cran.r-project.org/doc/manuals/r-release/Radmin.html#macOS,
where I read
------
One way to use these builds with a binary distribution of R is to have a
~/.R/Makevars file similar to (El Capitan)
FC = /usr/local/gfortran/bin/gfortran
FLIBS = -L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0
-L/usr/local/gfortran/lib -lgfortran -lquadmath -lm
or (Sierra or High Sierra)
FC = /usr/local/gfortran/bin/gfortran
FLIBS = -L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin16/6.3.0
-L/usr/local/gfortran/lib -lgfortran -lquadmath -lm
------
I naively chose the "Sierra or High Sierra" alternative, but that was
wrong as you can see: It apparently refers to gfortran 6.3, so I
switched to the the "El Capitan" alternative.
The final error message was then something about 'unable to compile
mixed C and Fortran code', and that was fixed by changing
LDFLAGS="-L/usr/local/clang7/lib -L/usr/local/lib"
to
LDFLAGS="-L/usr/local/clang7/lib -L/usr/local/gfortran/lib
-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0"
and voila, ./configure run without complaints!
The later build also went smoothly (but I had to install java).
So, to sum up, there seems to be some discrepancy between the two
instruction sets I tried to follow.

/usr/local/clang7 is likely a better place to look. Check out Appendix
C.3 of the R Inst.&Adm. manual:
https://cran.r-project.org/doc/manuals/r-release/R-admin.html#macOS
That's better! After correcting some obvious(?) errors(?) in that page,
./configure run without errors! (Had only read mac.r-procject.org/tools/
so far).
After a night's sleep I will 'make'. I'll report back to r-sig-mac.
Thanks, Göran

Update: There is a libgcc_s.1.dylib in /usr/lib, as a symlink to
/usr/lib/libSystem.B.dylib. Is that one useful?

Thanks Peter,
The tripping lines are here

so it seems as if my installation of tools is lacking an essential
part (/usr/local/lib/libgcc_s.1.dylib). I'll look around, but any
suggestion is welcome!

I can't claim to understand this, but on my system of same age,
using system clang, configure does complete. It does get that error
on line 23748, but that, and several similar subsequent tests just
end up returning "yes".

configure:23748: gcc -arch x86_64 -c -g -O2 -I/usr/local/include

1 error generated.
[..snip..]
configure:23748: result: yes
(as usual, configure code is nigh on unreadable, but I think the
logic is that the size_t type exists if you can do "sizeof
(size_t)", but not "sizeof ((size_t))", so the error is expected.)
The line that trips you up comes later:
configure:24611: checking size of size_t
configure:24616: gcc -arch x86_64 -o conftest -g -O2
-I/usr/local/include -L/usr/
local/lib conftest.c -ldl -lm >&5
configure:24616: $? = 0
configure:24616: ./conftest
configure:24616: $? = 0
configure:24630: result: 8
so that is where you should look for clues (or at least tell us
what it says there).

Hello,
I'm (for the first time) trying to build R-devel from source (to

My MacBook Pro is old (2010), so I am stuck with MacOS 10.13.6,
XCode 10.1. I'm using clang 7.0.0 and fortran 6.1.0.
Do I need to buy a new Mac?
Thanks, Göran
