compile-time warnings on Solaris 8 64-bit sparc (gcc 4.1.0)

[Paul Eggert]

Hey, congratulations on the new version!

On Solaris 8 (sparc) with GCC 4.1.0 installed, I built GNU make 3.81
as follows:

./configure --prefix=/r/share1/src/make CC='gcc -m64'
make

and got some worrisome warnings as shown below.  Spot-checking some of
the generated machine code, it appears to be OK, but it'd be nicer
if 'make' didn't generate those warnings.

Would you be open to modifying 'make' to use the alloca-opt module
from gnulib?  It would kill off most of these warnings, I think.
Other GNU programs use this module so 'make' would be in good company.

Here's the output of the above-mentioned commands.
