Usage: python includes.py library_includes application_includes winheaders.txt
The script includes.py finds out what application files include library headers that transitively includes windows.h or another Windows header.
library_includes is the output from grep -R -n include . in the directory
specified by Boost as the include dir.
boost-1_44_64_includes.txt is an example (Boost 1.44 on Windows 64-bit).
application_includes is the output from grep -R -n include . in your
application directory.
app_includes.txt is an example (TPIE).
winheaders.txt contains the offending headers (for instance the headers in the Windows API).
The script computes the include edges in each specified grep include file,
and computes the transitive closure from the winheaders to library headers.
Then for each library header that transitively includes a winheader,
if that header is included by an application file, this is reported.
