It appears that the problem is with AC_HEADER_STDC, which is reporting
that this setup does not have stdc headers when in fact it does.
Overriding with
 CFLAGS='-fvisibility=default -mmacosx-version-min=10.10
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include
-fPIC -pipe -DSTDC_HEADERS -DOPAL_STDC_HEADERS'
in particular, the last two defines, fixes this.

I don't know how that compares to upstream clang v7.x...?

More info:
Configured with
A few notes on your configure line:
'/Users/cary/projects/ulixesall-llvm/builds/openmpi-4.0.1/nodl/../configure' \
--prefix=/Volumes/GordianStorage/opt/contrib-llvm7_appleclang/openmpi-4.0.1-nodl
\
CC='/Volumes/GordianStorage/opt/clang+llvm-7.0.0-x86_64-apple-darwin/bin/clang'
\
CXX='/Volumes/GordianStorage/opt/clang+llvm-7.0.0-x86_64-apple-darwin/bin/clang++'
\
The MPI C++ bindings are no longer built by default, and you're not enabling
them (via --enable-mpi-cxx), so you don't need to specify CXX or CXXFLAGS here.
FC='/opt/homebrew/bin/gfortran-6' \
F77='/opt/homebrew/bin/gfortran-6' \
F77 is ignored these days; FC is the only one that matters.
CFLAGS='-fvisibility=default -mmacosx-version-min=10.10
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include
-fPIC -pipe -DSTDC_HEADERS' \
Do you need all these CFLAGS? E.g., does clang not -I that directory by
default (I don't actually know if it is necessary or not)? What does
-DSTDC_HEADERS do?
CXXFLAGS='-std=c++11 -stdlib=libc++ -fvisibility=default
-mmacosx-version-min=10.10
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include
-fPIC -pipe' \
FCFLAGS='-fPIC -pipe' \
--enable-static \
--with-pic \
--disable-dlopen \
--enable-mpirun-prefix-by-default
I don't have that version of clang, but I installed gfortran 6.3.0 via homebrew
and configured with:
./configure --prefix=/Users/jsquyres/bogus CC=clang FC=gfortran
'CFLAGS=-fvisibility=default -mmacosx-version-min=10.10
-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include
-fPIC -pipe -DSTDC_HEADERS' 'FCFLAGS=-fPIC -pipe' --enable-static --with-pic
--disable-dlopen --enable-mpirun-prefix-by-default
And Open MPI v4.0.1 build ok for me...?
