Using gcc 1.36 on a Sun 4, I have a program which is 12K in length and
uses one function (anint) from the math library.  The .o file is 48K,
but when the entire program is compiled with -lm, the executable is
160K, which is still 152K when stripped.  As a comparison, cc gives a
32K .o file and a 40K executable.

Is gcc including the *entire* math library in the executable, or
something similar?  And if so, is there any way to get a shorter
executable (other than writing the function and not including the
library)?  I would prefer not to keep a 160K executable around.
