AIUI Maxint is a Pascal Cosnstant, INT_MAX otoh is supported by my
compilers, .  INT_MIN is negative and (usually) one
larger than INT_MAX.

ints are between INT_MIN and INT_MAX

chars can be negative too if signed. both my compilers default to signed
characters, but I think unsigned is possible using a command-line option,
but that won't effect the behavior of library functions...
