#176 Slow and unresponsive parsing of boost

Related: https://sourceforge.net/p/orwelldevcpp/tickets/92/.

On Windows 10, 64bit, Dev-C++ version 5.11 takes a long time to parse boost odeint.

To reproduce, put boost in C:\Program Files (x86)\Dev-Cpp\MinGW64\include\boost, open Dev-C++ and add path to C++ includes under Compiler Options. Open a new file and type #include <boost/numeric/odeint.hpp> and save. Parsing the file for the first time takes 250 seconds on an i5, during which Dev-C++ is unresponsive. The slow parsing behavior repeats when Dev-C++ is closed and re-opened.
