We may want to configure m4 with:

./configure --prefix=/usr  --enable-threads

for a complete build.  I don't know if we want to consider libsigsegv or not.  I 
don't know of anything other than m4 that uses it.  Actually this is the first 
I've heard of it, but it may be useful.

It builds with:

./configure --prefix=/usr --enable-shared
  make
  make check
  make install

It takes less than 0.1 SBU and installs:

./usr/include:
