Description of Problem:

Hello there,

I just tried to compile package units-1.74-4 from Redhat 8.0.

Here are some of the compiler messages.

units.c:1199: warning: suggest parentheses around comparison in operand of &
units.c:1514: warning: `sep' might be used uninitialized in this function
units.c:1514: warning: `right' might be used uninitialized in this function
units.c:1514: warning: `left' might be used uninitialized in this function

Here is a bunch of patches which fix the messages.
