[R-pkg-devel] AlgDesign C Issue

[Jerome Braun]

Hi Michael!

I'd like to make the smallest change possible to Bob Wheeler's original
code so I'm not sure if using <stdbool.h> is the best route forward.

I do see that the definitions are the same there.  Is there a low-cost way
to use that header file or just those definitions?

Thank  you!
