64-bit solaris, gcc

Hi all,

I've gotten the boost libraries to build in 64 bit mode on Solaris by
running 
the following command right after unpacking the tar ( from boost root ):

bjam "-sBUILD=<cxxflags>-m64 <linkflags>-m64" stage

However, the libraries appear to be flawed, and I want to run the
regression tests to determine if they are indeed so. Sadly, they fail
to compile in 64-bit mode. Basically, this is because the
boost::filesystem shared archive has its contents in 32-bit objects,
because the 64-bit ones apparently fail to build. I've traced the
failure of the 64-bit filesystem compile down to the following compile
command:

g++ -c -Wall -ftemplate-depth-100 -g -O0 -fno-inline -m64 
-I"../../../bin
/boost/libs/filesystem/build"
-I"/home/analysis3/iyho/lib/boost_1_31_0-64" -I "
/home/analysis3/iyho/lib/boost_1_31_0-64" -o
"../../../bin/boost/libs/filesyste
m/build/libboost_filesystem.a/gcc/debug/exception.o" 
"../../../libs/filesystem/
build/../src/exception.cpp"

This produces the following errors:

cc1plus: -m64 is not supported by this configuration
cc1plus: -mptr32 not allowed on -m64
../../../libs/filesystem/build/../src/exception.cpp: In function
`class string 
{anonymous}::system_message(int)':
../../../libs/filesystem/build/../src/exception.cpp:79: internal error--
unrecognizable insn:
(insn 26 24 28 (set (reg:DI 109)
(symbol_ref:DI ("errno"))) -1 (nil)
(nil))

When I switch the -m64 flag to -m32, the exception.cpp file builds fine.

Any ideas? Has anyone had success building a 64-bit version of boost on 
Solaris? If so, what needed to be done?

Thanks,

Isaac
