I learned the other day, that MMS' "patsubst" is not compatible with GNU Make's one. And because MMK claims to be compatible with MMS, I should remove all the "expected output" from GNU Make.

Probably related:

$ type descrip.mms
all :
        @ write sys$output "$(patsubst %.c,%.o,a.c b.c foobar.c c.x.c)"
$ mmk/ext
a.o b.o f o a . c. .
$

Expected output:

$ mms/ext

a.o b.o foobar.c c.x.c
$ 

The documentation for MMS talks about two wildcard characters: '%' and '*'. GNU Make's patsubst accepts only one: '%'. And the meaning of '%' is different in MMS and GNU Make. Unfortunately the meaning of the wildcard characters isn't made clear in the MMS documentation.

This gives more test cases:

$ type descrip.mms
all :
        @ write sys$output "$(patsubst *.c,%.o,a.c b.c foobar.c c.x.c)"
$ mmk/ext
a.o b.o f.o c. .c
$ 

Expected output:

$ mms/ext

a.o b.o foobar.o c.x.o
$ 

And

$ ty descrip.mms
all :
        @ write sys$output "$(patsubst *.c,*.o,a.c b.c foobar.c c.x.c)"
$ 
$ 
$ mmk/ext
a.o b.o foobar.o c. .c
$ 

Which shows that the two wildcard characters of MMS are supported but work differently when used in the replacement.

Probably unrelated:

$ type descrip.mms
all :
        @ write sys$output "$(patsubst %.c,%.o,a.c b.c foobar.c c.x.c,)"
$ mmk/ext
%MMK-W-TOOMANYARGS, too many function parameters for 'PATSUBST'

$ 

Expected output:

$ mms/ext

a.o b.o foobar.c c.x.c,
$ 

There are probably more differences between MMS and MMK in this area:

$ type descrip.mms
all :
        @ write sys$output "$(patsubst *%.c *.z,*.*.o,a.c b.c foobar.c c.x.c x.y.z)"
$ 
$ mmk/ext
a.c b.c foobar.c c.x.c x.y.z
$
$ mms/ext

.a.o .b.o fooba.r.o c..x.o x.y.*.o
$ 

And yes, that's the way it is in MMS, whether MM% should do the same as GNU Make is a different question.
