# There are two regex.h headers: one is a standard system header (usually
# in /usr/include) and the second one is provided by boost. If you specify the
# path to boost in a way that specifies the actual directory, this will mess up
# the code and we'll end up using the system header rather than the boost. For
# example, if your boost headers are in /usr/local/include/boost, you should
