## There are various ways to get dependency output from gcc.  Here's
81
## why we pick this rather obscure method:
82
## - Don't want to use -MD because we'd like the dependencies to end
83
##   up in a subdir.  Having to rename by hand is ugly.
84
##   (We might end up doing this anyway to support other compilers.)
85
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
86
##   -MM, not -M (despite what the docs say).
87
## - Using -M directly means running the compiler twice (even worse
88
##   than renaming).

## This next piece of magic avoids the `deleted header file' problem.
106
## The problem is that when a header file which appears in a .P file
107

108
