fixdep parses dependency files (*.d) emitted by the compiler. *.d files are Makefiles describing the dependencies of the main source file. fixdep understands minimal Makefile syntax. It works well enough for GCC and Clang, but not for rustc. This commit improves the parser a little more for better processing comments, escape sequences, etc. My main motivation is to drop comments. rustc may output comments (e.g. env-dep). Currentyly, rustc build rules invoke sed to remove comments, but it is more efficient to do it in fixdep.
