I think that's a problem.  The GPL does not allow code to be used in a
program with a different licence.  Now this is part of the build
system, not part of the program itself, so it would be OK to use it,
but only if you do not distribute |acinclude.m4|.  If you distribute
|acinclude.m4| itself, and not just the program that it builds, then
this looks like a violation to me.  I think you should tell
Mr. Schilling what you are doing, and ask for a copy under LGPL, 
BSD, or similar licence.
