Hello,
When building flex on clang 8.0.1 (i386) I noticed that assert()
expands to nothing. This happens because of a fallback declaration
of assert() in flexdef.h when HAVE_ASSERT_H is not set. Instead of
changing flexdef.h the following patch follows the existing pattern
in Makefile of adding -DHAVE_SOMETHING. Does this look OK?
