3758	"Using Boost Testing Framework from Boost.build Jamfile generates warning about ""long long integer constant"" with gcc 4.2.2"	Guillaume Chatelet <chatelet.guillaume@…>	Gennadiy Rozental	"Hello everyone,

I'm using Boost.Build to automate testing. The Jamfile.v2 is as follow

{{{
import testing ;

use-project /boost : /path/to/boost ;

path-constant INCLUDE_PATH : path/to/include ;
path-constant SOURCE_PATH : $(INCLUDE_PATH) ;

project
    : requirements      <define>BOOST_TEST_MAIN
                        <threading>multi
                        <include>$(INCLUDE_PATH)
    ;

alias dependencies
    :
                /boost//unit_test_framework
                [ glob $(SOURCE_PATH)/*.cpp ]
    ;

run   main.cpp dependencies ;
}}}

so invoking /boost//unit_test_framework refers to boost unit testing framework's project.

My test passes but while compiling the unit_test_framework libraries it generates the following warning ( gcc 4.4.2 )
{{{

}}}

looking at the tests of boost unit testing framework ""boost/libs/test/test/Jamfile.v2"" I noticed it was already corrected  in the tests but not in the build.

{{{
rule test-btl-lib ( test-rule : test-name : lib-name ? : pattern_file * : source_files * : extra-libs ? )
{
   source_files ?= $(test-name).cpp ;

   return [ $(test-rule) $(source_files) ../build//$(lib-name) $(extra-libs)
            : #args
            : $(pattern_file)
            : #<stlport-iostream>on
              # Activating -pedantic finds more gotchas
              # Unfortunately, this warns about the use of ""long long"" in gcc's own stdlib
              # So deactivate those warnings again
              <toolset>gcc:<cxxflags>-pedantic
              <toolset>gcc:<cxxflags>-Wno-long-long
              <toolset>borland:<cxxflags>-w-8080
              <toolset>msvc-6.5:<link>static
              <toolset>msvc-8.0:<define>_SCL_SECURE_NO_DEPRECATE
              <warnings>all
            : $(test-name)
          ] ;
}
}}}

It seems my test project triggers the -pedantic flag and then gcc complains about ""long long"".

I'd like to activate the <warning-as-errors> flag for my whole project and this warning about ""long long"" prevents me to do so.

Can you consider my patch to apply the same workaround as for tests ?
