 No, I am not using PCH.  I'm trying to use the --include switch but it
 isn't recognized by C++ as a switch with 2 arguments and so it gets
 improperly handled.  It ends up reordering my switches and passes -O2 as
 the file to include and tries to compile the include file as an input
 file.
 
 So I observed that
 
 gcc -include hack.h -O2 test.cc
 
 would end up as
 
 switches:
 -include -O2
 
 input files:
 hack.h test.cc
 
 thus it would fail because it cannot find the file "-O2" and because it
 would precompile hack.h into hack.pch.
