* libU77/u77-test.f: Don't bother declaring etime.
Use `implicit none' and declare mask and lenstr.
Do ETIME/DTIME consistency check before loop, then
use loop to verify that dtime "ticks" at some point.
Check ETIME array-sum using single-precision add, to
avoid spurious complaint on systems (like x86) that
use more precision for intermediate results.
Fix `Results of ETIME and DTIME...' message to print
pertinent values (r1 and r2 instead of i and j).
Change loop from 10M to 1K repeated up to 1000 times
or until dtime "ticks".
Print the number of 1K loops needed to see this tick.
Answer a commented question.
Split up a long line of output and do other prettying.
Preset lognam in case GETLOG fails to overwrite it.
Patch from Craig.
