Make min/typ/max default warning message universal. 

The min/typ/max default warning was not being produced in all
locations a min/typ/max expression could be used. This patch
adds the default warning code to all locations. It also
modifies the manual page to explicitly state that only the
first ten warnings are printed.

.B -T\fImin|typ|max\fP
Use this switch to select min, typ or max times from min:typ:max
expressions. Normally, the compiler will simply use the typ value from
these expressions (with a warning) but this switch will tell the
compiler explicitly which value to use. This will suppress the
warning that the compiler is making a choice.
