Hi,
I'm trying to build Boost1.39.0 on interix which is a UNIX subsystem running on top of the NT kernel for Windows XP and Vista. MS provides it as an optional add-on.
The compiler I'm using is an experimental port of GCC4.4.0 as there isn't any recent GCC port around for interix. So far I'm able to build medium sized C++ projects with the compiler so I believe it's working. 
Having tried to set up boost has so far proved problematic. A bootstrap.sh run followed by a bjam run results in compiler errors such as:

    "g++"  -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -pthread -fPIC  -DBOOST_ALL_NO_LIB=1 -DBOOST_MATH_TR1_DYN_LINK=1 -DNDEBUG  -I"." -c -o "bin.v2/libs/math/build/gcc-4.4.0/release/threading-multi/asinh.o" "libs/math/build/../src/tr1/asinh.cpp"
...failed gcc.compile.c++ bin.v2/libs/math/build/gcc-4.4.0/release/threading-multi/asinh.o...
gcc.compile.c++ bin.v2/libs/math/build/gcc-4.4.0/release/threading-multi/atanh.o
g++: unrecognized option '-pthread'

I know that on interix -pthread should be replaced by -lpthread and that GCC on interix currently doesn't support -fPIC. Does anybody know where I can amend these compiler flags? 

Many thanks,

Robert
