dnl aclocal will actually find and include them automatically, but before it

dnl does it might fully scan all other system installed m4 files. Doing this

dnl explicit inclusion also allows us to override definitions of macros done

dnl elsewhere in other packages with the ones done in our included files.

m4_include([m4/reentrant.m4])

m4_include([acinclude.m4])
