I think i mentioned that already a few times, there's an utility that
post-process whatever cl has to offer and output make style dependency
information. Works on both windows and unix (cl in this case runs via
WINE and the tool goes through the trouble of dealing with drive
letters, fixing the paths, case sensetiveness and so on) The tool is
written in OCaml. And is in fact integrated into my own OMake based build
system.

imt dep subcommand parses /E output
imt dep7 uses /showIncludes

a.c that is present in the transcript is what ends in stderr, i.e. it
is safe to redirect this output or let OMake deal with it in .SCANNER
rule.
