#### boost is not found
Try and change the include dir to use the windows path from c like this: Edit compiler/cpp/Makefile, look for the declaration of BOOST_CPPFLAGS, change that line for
- BOOST_CPPFLAGS = -Ic:/cygwin/usr/include/boost-1_33_1
+ BOOST_CPPFLAGS = -Ic:/cygwin/usr/include/boost-1_53_0
#### realpath is not found
add -DMINGW -mno-cygwin to the CXXDEFS variable in Makefile
