# Test for PR 34.
# > Description:
#  Automake fails to add -I option to include configuration
#  header indicated like AM_CONFIG_HEADER(magick/config.h)
# > How-To-Repeat:
#  Use AM_CONFIG_HEADER(subdir/config.h) to place configuration
#  header in subdirectory and observe that it is not included.
# Also check that our preprocessing code is smart enough not to pass
# repeated '-I<DIR>' options on the compiler command line.
