## up in a subdir. Having to rename by hand is ugly. |
155 |
## (We might end up doing this anyway to support other compilers.) |
156 |
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like |
157 |
## -MM, not -M (despite what the docs say). Also, it might not be |
158 |
## supported by the other compilers which use the 'gcc' depmode. |
159 |
## - Using -M directly means running the compiler twice (even worse |
160 |
## than renaming). |

## This next piece of magic avoids the "deleted header file" problem. |
178 |
## The problem is that when a header file which appears in a .P file |
179 |
## is deleted, the dependency causes make to die (because there is |
180 |
## typically no way to rebuild the header). We avoid this by adding |
181 |
## dummy dependencies for each header file. Too bad gcc doesn't do |
182 |
