Maybe I'm simply unaware of some subtle issues, but I don't know of
any situation where this cannot be done safely.  In particular, the
code I wrote for GNU Make works since the release of Make 3.81, and I
have yet to see any problems with interrupting a running Make, or hear
a single complaint or bug report related to C-c.
