I have a sparc64 box (SunFire 880) here, running a beta of
Solaris 10.  It happens Solaris 10 seems to have the same
lame /bin/sh that solaris has for quite a while, and it won't
run build.sh.  When I try, it says:

% ./build.sh -m sparc64 release
./build.sh: bad substitution
%

   Now, this is each to work around by invoking ksh, but
without some way to tell build.sh that it needs to be run
under ksh, it will quickly fail as:

% ksh ./build.sh -m sparc64 release
===> build.sh command: ./build.sh -m sparc64 release
===> build.sh started: Mon Jun 14 16:02:16 EDT 2004
===> No nonexistent/bin/nbmake, needs building.
===> Bootstrapping nbmake
checking for sh... /usr/bin/sh
checking for gcc... cc
checking for C compiler default output... configure: error: C compiler 
cannot create executables

ERROR: Configure of nbmake failed
*** BUILD ABORTED ***
%

   Okay, this is a compiler problem.  Also an issue, but
I'll post another email about that.  Fix that, and:

% HOST_CC=gcc ksh ./build.sh -m sparc64 release
===> build.sh command: ./build.sh -m sparc64 release
===> build.sh started: Mon Jun 14 16:03:33 EDT 2004
===> No nonexistent/bin/nbmake, needs building.
===> Bootstrapping nbmake

.
.
gcc  -O -o nbmake *.o
/usr/bin/sh: bad substitution

Stop.

   So, it's invoking /usr/bin/sh somewhere, which is failing
to parse the file.

   How do I tell build.sh, and the constructed nbmake, to
use /usr/bin/ksh, instead of /usr/bin/sh, in all cases?

   Thanks...
