make versus _MANPAGE

[Gerald Pfeifer]

Is the following a ports/Mk bug, a /usr/bin/make bug, or just bad
carma?  Seen on 4.8-p13 and 5.2-CURRENT.


I am currently fighting a very nasty problem where a construct involving
.for in a Makefile works as expected, depending on whether I use it before
.include <bsd.port.post.mk> or after.

It's exactly the same code in both cases, and also the ${_MANPAGES}
variable is properly set in both cases!

To reproduce, just apply the patch above on the lang/gcc33 port and
exercise two targets added by the patch:

  % make before
  /s/scratch/gerald/man/man1/cpp33.1 /s/scratch/gerald/man/man1/g++33.1
  :
  /s/scratch/gerald/man/man7/gpl.7
  ===============================
  begin
  end

Where are all those man pages gone?

  % make after
  /s/scratch/gerald/man/man1/cpp33.1 /s/scratch/gerald/man/man1/g++33.1
  :
  /s/scratch/gerald/man/man7/gpl.7
  ===============================
  begin
  /s/scratch/gerald/man/man1/cpp33.1
  :
  /s/scratch/gerald/man/man7/gpl.7
  end

In this case, after the .include <bsd.port.post.mk> it works?
