Fortunately, in Solaris where I am testing the import of sys/cdefs.h and
sys/queue.h today, things seem to be `ok'.  Just importing the two
headers at seems to have
moved things one step closer towards building everything on Solaris:

Now off to the next little annoyance.  Building with Sun Studio on
Solaris 10, in my test machine at home, stops at:

  "arch.c", line 1063: undefined symbol: INT_MIN
  cc: acomp failed for arch.c
  *** Error code 2
  make: Fatal error: Command failed for target `arch.o'
  Current working directory /home/keramida/bmake/src

This is easy to fix with:

  diff -r 68bfc25ed443 src/arch.c
  --- a/src/arch.c        Tue Mar 04 17:29:11 2008 +0200
  +++ b/src/arch.c        Tue Mar 04 17:35:08 2008 +0200

The next part, about the missing errx() functions on Solaris is going to
be tonight's fun.  If there are too many missing functions, it may be
worth adding a static `libcompat' with copies of just the functions we
need to run BSD make on non-BSD hosts.
