Java front-end dependency on GNU make?

[Bret McGuire <mersault at busboy dot sped dot ukans dot edu>]

	In a recent discussion yesterday regarding which version of gperf
was necessary to build egcs from CVS, Robert Lipe mentioned that any
dependence on gmake had allegedly been eliminated.  Shortly after this
conversation, I noticed a build problem with the current snapshot as
obtained through CVS...
	For the record, all this is being built on an Alpha running
Digital UNIX v4.0D.  I tried the initial compile using Digital's make and
ran into a problem with the Makefile for the new Java front-end.  The
generated Makefile is included as an attachment to this message so you can
see specifically what I'm talking about.  That build bombed, but worked
much better once I switched to GNU's make.
	Here are the results which I saw; "make" is GNU make v3.77 and
"make.digital" is the make program that comes with Digital UNIX v4.0D:

bash# pwd
/usr/local/egcs/egcs/gcc/java
bash# make
gcc -c  -DIN_GCC    -g     -I. -I.. -I. -I./.. -I./../config
-I./../../include parse.c
make: *** [parse.o] Interrupt

bash# make.digital
Make: Makefile: Must be a separator on line 97.  Stop.
bash# make -v
GNU Make version 3.77, by Richard Stallman and Roland McGrath.
[snip, snip]
bash# make.digital -v
Make: Unknown flag argument v.  Stop.

	So I wonder... do we still have at least a minimal dependency on
GNU's make?  Or is Digital's make just broken beyond help?  There was a
patch put out by Digital for make on a 4.0D system, but that patch has
been applied to this system, so that can't be the cause.
	Any ideas, or am I just being a nuisance? :)
