Many warnings appear because GNU make up to and including 3.81 is still
attempting to build properly with old K&R C compilers.  That's also the
reason it cannot make use of gnulib modules, since gnulib requires C89.


A few months ago I decided that 3.81 would be the last version that
attempted to support K&R C, and that as of 3.82 GNU make would require a
ISO C (89) compiler.  I have several workspaces in which I'm cleaning up
code in the following ways:

  * Removing all the PARAMS() macros.
  * Changing char to void wherever appropriate.
  * Changing from BSD-style functions like bcopy to ISO C functions like
    memcpy/memmove.
  * Const-ifying as necessary.

And other cleanups.  As you can imagine, this will cause a lot of churn
in the code.  After it is compiling and working properly for UNIX I'm
planning on creating a 3.81.90 release so that the other ports can make
the appropriate changes to their parts of the code.

At that time it would be a good idea to look through gnulib etc. for
opportunities for re-use.


Thanks!


PS. I checked the gnulib manual on the gnu.org website and there's no
    mention of alloca-opt there??
