They separate the autoconf macros needed to determine _when_ to enable a
replacement from the autoconf macros needed for compiling the replacement.
The purpose is that when you change the source code of the .c file you need
to proofread only half of the implementation.

Also, sometimes we use the same .c file in two different modules; here also
it helps.
