Subject: Add stdbool.h plus fallback to h/nmh.h.
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/40009883832750cb536db4d41f500c0ad41005de?hp=ffdd694f6050652d492606e5adbcb5f491050ace

Add stdbool.h plus fallback to h/nmh.h.
Change h/mh.h's FALSE and TRUE to use stdbool.h's.  In time, everything
can switch over and FALSE and TRUE can go.  Delete some local
re-definitions of FALSE and TRUE.
