make vs. gmake in 6-CURRENT...

Hi, all--

Apparently something has changed with BSD make in -CURRENT, causing the 
following problem to appear in a port I maintain:

[ ... ]
===>  Installing for dvd+rw-tools-5.21.4.10.8
===>   dvd+rw-tools-5.21.4.10.8 depends on file: /usr/local/bin/mkisofs  - found
===>   Generating temporary packing list
install  -s -o root -g wheel -m 555 
/usr/ports/sysutils/dvd+rw-tools/work/dvd+rw-tools-5.21.4.10.8/ growisofs 
/usr/local/bin
install:  /usr/ports/sysutils/dvd+rw-tools/work/dvd+rw-tools-5.21.4.10.8/ 
growisofs: No such file or directory
*** Error code 71

Note the space in ".../dvd+rw-tools-5.21.4.10.8/ growisofs", which command was 
generated by the following Makefile section:

do-install:
.for i in ${BIN_FILES}
         ${INSTALL_PROGRAM} ${WRKSRC}/${i} ${PREFIX}/bin
.endfor

Since I don't have a system running 6, I was fortunate to have someone look 
into the issue and fix the port by having it use gmake instead. (thanks BTW)

However, it seems like that space-stuffing when generating paths would break 
lots of other things.  Anyway, I wanted to bring up the issue here and ask 
whether this change to make's behavior is expected or whether it should be 
considered a bug...?

Cheers,
