the space is not allowed; in m4, the left parenthesis as to follow
the macro name immediately.

I tried to make an example.  The main trick seems to be to get all
the include directories.  `pkg-config' can help you with that.

Well, pkg-config has some Autoconf macros, but I ignore them right
now.  (Do they support the --cflags-only-I option somehow?)

Here is the example:

AC_INIT([foo], 1.0, address@hidden)
save_CPPFLAGS=$CPPFLAGS
CPPFLAGS="$CPPFLAGS `pkg-config --cflags-only-I libgtkhtml-2.0`"
AC_CHECK_HEADER([libgtkhtml/gtkhtml.h],
        [],
        [AC_MSG_ERROR([BUMMER, Maybe if you install libgtkhtml-2 & 
libgtkhtml-2-dev this pig will fly])])
CPPFLAGS=$save_CPPFLAGS
AC_OUTPUT


Enjoy,
        Stepan
