# ABIGAIL_INIT
#
# Handle the detection of the libabigail header and library files on
# the system. If these are present, set the 'abigailinc' variable to
# the compiler option necessary to locate the headers of the library;
# also set the 'abigaillibs' variable to the compiler/linker option
# necessary to locate the library.
#
# Note that this macro defines the handling of --with-abigail,
# --with-abigail-include, --with-abigail-lib and
# --enable-abigail-version-check switches to the configure script.
#
# If libabigail has been found, this macro sets the variable
# HAVE_LIBABIGAIL to 'yes', otherwise, it sets it to 'no'.
