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

96 | ## This next piece of magic avoids the `deleted header file' problem. | ||
97 | ## The problem is that when a header file which appears in a .P file | ||
98 | ## is deleted, the dependency causes make to die (because there is | ||
99 | ## typically no way to rebuild the header). We avoid this by adding | ||
