 108 ##   up in a subdir.  Having to rename by hand is ugly.
 109 ##   (We might end up doing this anyway to support other compilers.)
 110 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
 111 ##   -MM, not -M (despite what the docs say).
 112 ## - Using -M directly means running the compiler twice (even worse

 131 ## The problem is that when a header file which appears in a .P file
 132 ## is deleted, the dependency causes make to die (because there is
 133 ## typically no way to rebuild the header).  We avoid this by adding
 134 ## dummy dependencies for each header file.  Too bad gcc doesn't do
