120
## why we pick this rather obscure method:

## - Don't want to use -MD because we'd like the dependencies to end
122
##   up in a subdir.  Having to rename by hand is ugly.
123
##   (We might end up doing this anyway to support other compilers.)
124
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
125
##   -MM, not -M (despite what the docs say).
126
## - Using -M directly means running the compiler twice (even worse
127
##   than renaming).

147
