# Rather than have libltdl run it's own configure, the few tests libltdl needed
# were added to the main configure.ac. As we need to look at config.h in header
# files, which may conflict with other versions of config.h, this has been
# renamed to gnashconfig,h to be unique. As the files libtoolize copies insist
# on using config.h, we just edit the name, rather than adding a fixed copy to
# Gnash.
#
# This gets more interesting with libtool 2.x, which heavily changed how everything
# worked. Where libtool 1.5 installed only a header and had a single source file,
# libtool 2.x has an entire sub directory tree of headers and source files.
# So for libtool 1.5.x, we do everything the way this has always worked for Gnash.
# For libtool 2.x, we install in a subdirectory of libbase, because we have to
# hack the build directory, and everything configures tottally differernt than 1.5.x
# used to. For more fun, libtoolize has different command line arguments, but one thing
# that got fixed is for libtool 2.x there is an #define for the config file name, but
# for libtool 1.5 it expects config.h always, so we change this to gnashconfig.h.
