I missed this aspect of your question.

In this case AC_CONFIG_FILES probably will not help at all and you will
have to do it with normal make rules.

How about something like this:

Makefile.am-fragment:
..
xxx_SOURCES = class1.cpp class2.cpp
CLEANFILES = class1.cpp class2.cpp

class1.cpp: main.cpp.in
	sed -e pattern1 < $(srcdir)/main.cpp.in > $@

class1.cpp: main.cpp.in
	sed -e pattern2 < $(srcdir)/main.cpp.in > $@

You'd probably have to setup the sed patterns in your configure.ac,
then.
