Preprocessor defines for True and False in libqhull_r.h

[kzampog]

Hello,

The preprocessor defines in:

qhull/src/libqhull_r/libqhull_r.h

Line 117 in 013e325

#define False 0

can cause problems with other libraries, as True and False are pretty common tokens (e.g., see https://github.com/stevenlovegrove/Pangolin/blob/master/components/pango_core/include/pangolin/utils/true_false_toggle.h).

If these are truly needed, would it be possible to have them renamed to something less likely to cause unwanted interactions?

Thanks!

Good suggestion. libqhull_r.h defines qh_True for users who want to avoid using 'True' in their code.

Since a rename affects almost all files and would break existing code, this change will be considered for the next release (hopefully some time next year).

This makes sense -- thank you!!

C99 also has <stdbool.h> which defines true and false.
