Milestone:  To Be Determined          |  Component:  mpl
  Version:  Boost 1.63.0              |   Severity:  Problem
 Keywords:                            |
--------------------------------------+------------------------------
 **How to reproduce:**

 Build System: Ubuntu 16.04.0 LTS
 GCC: all

 Let's say that we have the boost sources in `/tmp/boost-linux/boost_1_X_X`

 The important thing is to have the string `linux` in the `boost-root`
 variable.

 **Error log:**

 }}}

 **Problem:**
 This appears because in `preprocess.cmd` gcc is invoked with include files
 included with angle brackets, so if we have the string `linux` it will be
 evaluated to `1` because it is a macro
