Clarify a feature and clang issue in 1991/dds

Browse Source 
The clang issue does have an alternate version which I made a while back
but I added a note earlier in the file that most likely it'll be needed
for clang - depends on the default CFLAGS possibly but for macOS at
least it does not work. I never tested linux but I probably should.
