It is quite standard.  I even think POSIX specifies it, but I don't have 
a POSIX reference handy to check.  Anyway, many Make programs support it, 
although if you want to also support Make programs from DOS compilers, 
you might consider staying away from static pattern rules.

Borland Make (at least the revisions of BC I use) is a 16-bit DPMI 
program, and it can never work with GCC.  16-bit and 32-bit DPMI clients 
cannot be mixed at all.  Beta 3 couldn't have supported this because this 
is a fundamental limitation of the DPMI spec.
