## GNU recode library test.  This file is in public domain.
## Defines:
## HAVE_LIBRECODE when have recode_new_outer() and recode.h
## LIBS (adds library when needed)

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.
