Cos and Sin broken in gcc-gnat 3.2 ?

Cos and Sin broken in gcc-gnat 3.2 ?

[Preben Randhol]

My small program Klokka works with no problem with Gnat 3.14p and GtkAda
1.2. I wanted to see if it worked with GtkAda 2.0 as well. It seems to
work except that the handles won't be painted correctly. After some
debugging I found out that whatever value I give to a Cosinus function I
get back a 6.72421E-4932.

   package Math is
         new Ada.Numerics.Generic_Elementary_Functions
            (Float_Type => Float);

I have defined my Math package like this.

Can anybody verify weather the Cosinus and Sinus functions work in
gcc-gnat 3.2 or if it has a error in them.

I'm using Debian Linux so there might be an error in the build of the
gcc-gnat 3.2 as well.

Thanks in advance.

PS: If you want to test the program with gcc-gnat 3.2 and GtkAda 1.2 it
can be found here: http://www.pvv.org/~randhol/Ada95/Klokka/

I was a bit unclear here. You need gcc-gnat 3.2 to compile GtkAda 2.0 so
I upgraded the compiler to 3.2

Dunno if this is fixed in 3.3x but the CVS 3.3x is a much better 
compiler than 3.2 *for* Ada.  ACT did a "big merge" after the 3.2 
release as AFAIK they haven't backported changes to 3.2 (which will soon 
be superceded by 3.3 - maybe they felt that back porting wasn't worth it 
given the frequency of gcc release).

Don't quote me on that btw!
