8256	Wave tests fail to build on OSX+GCC	chris0@…	Hartmut Kaiser	"When attempting to build & run the Boost (1.53.0) wave tests on OSX 10.8.2 with GCC 4.2.1 the build fails at the link stage.

I built with:[[BR]]
    cd boost_1_53_0/libs/wave/test/build[[BR]]
    b2 variant=debug

The invocation:
{{{
g++-4.2 -o ""../../../../../build/libs/wave/test/build/test_re2c_lexer.test/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/test_re2c_lexer""  ""../../../../../build/libs/wave/test/build/test_re2c_lexer.test/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/test_re2c_lexer.o"" ""../../../../../build/libs/date_time/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_date_time.a"" ""../../../../../build/libs/thread/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_thread.a"" ""../../../../../build/libs/filesystem/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_filesystem.a"" ""../../../../../build/libs/system/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_system.a"" ""../../../../../build/libs/program_options/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_program_options.a"" ""../../../../../build/libs/wave/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_wave.a"" ""../../../../../build/libs/chrono/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_chrono.a"" ""../../../../../build/libs/date_time/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_date_time.a"" ""../../../../../build/libs/thread/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_thread.a"" ""../../../../../build/libs/filesystem/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_filesystem.a"" ""../../../../../build/libs/system/build/gcc-4.2/debug/link-static/runtime-link-static/threading-multi/libboost_system.a"" -g -static -isysroot /Developer/SDKs/MacOSX10.5.sdk
}}}
produces the message:
{{{
ld_classic: can't locate file for: -lcrt0.o
collect2: ld returned 1 exit status
}}}

However, removing the '-static' flag fixes the problem.[[BR]]
(On OSX 'man ld' reports ""-static     Produces a mach-o file that does not use the dyld.  Only used building the kernel."".)

The problem appears to be in boost_1_53_0/tools/build/v2/tools/gcc.jam. Due to these lines (767):
{{{
if [ os.name ] != HPUX
{
    toolset.flags gcc.link OPTIONS <runtime-link>static : -static ;
}
}}}

I was forced to change this, like so, to work around the problem:
{{{
#if [ os.name ] != HPUX && [ os.name ] != darwin # Doesn't work
#if [ os.name ] != HPUX && [ os.name ] != posix # Doesn't work
if [ os.name ] != HPUX
{
#    toolset.flags gcc.link OPTIONS <runtime-link>static : -static ;
# Had to comment out above line for OSX/darwin
}
}}}

Once built the tests all run successfully.
