## GNU recode library test. This file is in public domain.

dnl Test for librecode.
dnl Braindead librecode depends on symbol program_name defined in main program
dnl this makes the test braindead too. In header file test, we have to use
dnl a whole load of fakes, since it depends e.g. on bool and FILE defined.
