Using Alsys Risc Ada (on Sun SS10, Solaris 2.3), how
do you make the math package available for use?
The following compiles fine but fails at link time:
with math_library; use math_library;
with TEXT_IO; use TEXT_IO;
procedure t is
package REAL_IO is new FLOAT_IO(FLOAT); use REAL_IO;
package new_math is new math(FLOAT); use new_math;
begin
put(asinh(sqrt(6.25)),1,4,0);
new_line;
end t;
% ada t.ada ; ald t

You probably need to give "ald" an extra link-time option to tell
it to include the math library.
I'm not a user of Alsys Risc Ada, but Rational VADS and most
Unix C compilers require such options also when you use
floating point operations.
See if "ald" supports a "-l" (library) option.
If ald works like some other linkers, you may just need to insert "-lm"
(library - math) after the "ald" command.
