+This test suite is a subset of one put together some years ago, as a
+regression suite for a different cpp.
+
+It was never intended to test for standards conformance, although if
+you look around you'll find that the mpp example gets quite a lot of
+things wrong.
+
+Some highlights:
+
+   badinc15.c		- crashes
+   badmac{03-06,17,18,20}.c - varargs macros not supported
+   badmac07.c		- allows multiple definition of macro arg names
+   badmac08.c		- allows arbitrary redefinitions of macros
+   badmac{09,10-14}.c	- allows undefining/redefining builtin macros
+   badmac{15,16}.c	- allows defining "defined"
+   badmisc{1,2}.c	- allows out-of-range line numbers
+   broken01.c		- passing empty macro args crashes
+   broken02.c		- doesn't allow macro expansions to span lines
+   broken{03-04}.c	- even simple recursive macros crash
+   broken05.c		- wrong number of macro args causes assertion
+   broken06.c		- nested token pasting crashes
+   broken07.c		- doesn't allow pasting to an empty token
+   broken08.c		- empty macro before directive causes strange error
+   broken{09,10,11}.c	- macros expanding to directive-like lines crash
+   broken12.c		- weird thing with #undef inside #if 0
+   error1.c		- apparently doesn't support #error
+   evil01.c		- crashes
+   evil02.c		- completely bogus error message
+   includes.c		- incorrect macro substitution in final #includes
+   length{01-06}.c	- crashes
+   line.c		- doesn't support line numbering?
+
+   misc.c
+		- doesn't splice continuation lines correctly in some cases
+		- doesn't handle // comments
+		- doesn't understand digraph tokens
+		- doesn't handle character constants in conditionals properly
+		- after #undef ifndef, #ifdef ifndef gives wrong answer
+		- doesn't handle nested expansion correctly
+		- allows pasting punctuation tokens together
