really need to be sure .h files are not getting multiply included
(I had thought this was already best-practice from the K&R days).
new rules for forming the symbol from the filename:
(1) capitalize each word of the filename,
(2) final 'H' is capitalized
... *unless* the rest of the filename is an initialism (AST, DB)
which would make the resulting symbol all-caps (AST_H, DB_H)
which we do not want (since it might collide with something real)
so use a small 'h' in those cases (AST_h, DB_h)
(3) make sure this preprocessor symbol is used *NOWHERE* else.
