-gnatW8 and Ada.Numerics

[Y.Tomino]

Hello.
I take -gnatW8 switch to use UTF-8 string literal with gcc-4.1, also I
want to use Ada.Numerics package.
But compiler reports "illegal wide character" error.

Test:
with Ada.Numerics;
procedure Test is
begin
  null;
end Test;

>gnatmake -gnat05 -gnatW8 test
gcc -c -gnat05 -gnatW8 test.adb
a-numeri.ads:24:04: illegal wide character
gnatmake: "test.adb" compilation error

How should I do to compile it ?
It seems allowed by the document:
> UTF-8 encoding (brackets encoding also recognized)
(http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gnat_ugn_unw/Character-Set-Control.html)

I tried with GNAT GPL 2006.
GNAT GPL 2006 can compile it.

It is most likely a compiler bug. Bug in the gcc version of GNAT should
be reported here:

Well, yes, but if it works in GNAT GPL 2006 then apparently the bug has 
already been fixed. The fix should get into GCC at the next merge, so 
it's not so important to report this.

I disagree.  All bugs should be reported and tracked in a database, no
matter what.

- Someone might find a workaround.
- People use GCC 4.1 and upgrading to GNAT GPL 2006 might not be an
option for everyone.
- GCC 4.1 is the current, production version of GCC. Even if it
weren't, this information is useful and valuable to all people who use
GCC 4.1 (or previous versions, if they also have the bug) for the years
to come.
