obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.
downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.
if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

If an implementation provides +-- package Interfaces.C, this test must compile, execute, and +-- report "PASSED". +-- +-- SPECIAL REQUIREMENTS: +-- The file CXB30040.C must be compiled with a C compiler. +-- Implementation dialects of C may require alteration of +-- the C program syntax (see individual C files). +-- +-- Note that the compiled C code must be bound with the compiled Ada +-- code to create an executable image. An implementation must provide +-- the necessary commands to accomplish this. +-- +-- Note that the C code included in CXB30040.C conforms +-- to ANSI-C. Modifications to these files may be required for other +-- C compilers. An implementation must provide the necessary +-- modifications to satisfy the function requirements. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- CXB30040.C +-- CXB30041.AM +-- +-- CHANGE HISTORY: +-- 30 Aug 95 SAIC Initial prerelease version. +-- 09 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. +-- 26 Oct 96 SAIC Incorporated reviewer comments. +-- 13 Sep 99 RLB Replaced (bogus) Unchecked_Conversions with a +-- C function character generator. +-- +--! + +with Report; +with Interfaces.C; -- N/A => ERROR +with Ada.Characters.Latin_1; +with Ada.Exceptions; +with Ada.Strings.Fixed; +with Impdef; + +procedure CXB30041 is +begin + + Report.Test ("CXB3004", "Check that the functions To_C and To_Ada " & + "produce correct results"); + + Test_Block: + declare + + use Interfaces, Interfaces.C; + use Ada.Characters, Ada.Characters.Latin_1; + use Ada.Exceptions; + use Ada.Strings.Fixed; + + Start_Character, + Stop_Character, + TC_Character : Character := Character'First; + TC_char, + TC_Low_char, + TC_High_char : char := char'First; + TC_String : String(1..8) := (others => Latin_1.NUL); + TC_char_array : char_array(0..7) := (others => C.nul); + + -- The function Char_Gen returns a character corresponding to its + -- argument. + -- Value 0 .. 9 ==> '0' ..
