 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 ?

 Best regards,
 Guillaume
