I cobbled up CMS Make (like three times, two being lost to former
employers) and intentionally made "leading white space" count for
"leading tab character". Seems to work, but I always only ever use a
subset of full 'make' capability (on any platform).
Anyway, it's not difficult to have your makefiles fix themselves,
converting leading 8 blanks to a tab automagically. Some of the
makefiles in and around CMS Make do exactly that: if they land on (for
example) Linux, they get run through 'sed' to convert leading 8 blanks
to a single tab.
The idea is that "makefile" (or "Makefile" if you must) depends on some
other "makefile.in", which is the master. On any platform, if
"makefile.in" is newer, the recipe is triggered, and maybe is just ...
sed 's#^ #\t#' < makefile.in > makefile
... or something to that effect. (Might have to embed a real tab if
your 'sed' is not smart enough.) Then you can edit your master rules
files on 3270 without funky presentation and painful data entry
incantations.
Makefile with dependencies is messy but not unheard of.

This is somehow more pernicious than punch-card-column dependencies in
traditional IBM tools? :)
IMO, the use of tabs as a "data character" is only annoying to people
stuck on a 3270 display. I have _no_ problems with them when I'm using ssh
to get a UNIX shell. Boiled down, I will agree that using UNIX tools in a
TSO (3270) environment is annoying. Equally annoying, to me, is the
column dependencies when I editing an HLASM or COBOL program from the UNIX
shell. And don't get me going on the "vi" that IBM distributes.
