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 http://hg.hellug.gr/bmake/gker/rev/68bfc25ed443 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

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.
