[Flex-devel] Does Flex still need K&R support?

[Joe K. <kr...@ni...>]

I added M4 macros to my modified skeleton to handle C and C++ functions 
with a single macro, instead of one macro for each argument count to add 
the reentrant argument. The idea was to simplify the skeleton body by 
having better M4 macros.

My current implementation is derived from Bison's macros. It doesn't 
look as pretty here because Flex uses double brackets, and results in a 
syntax that is not really nicer looking than the previous method. It 
will be easier to simplify the macros if K&R support is dropped. Does 
anyone in the world still need it? If so, they can always use an older 
release of Flex.
