it is AC_PROG_LIBTOOL that checks these header files. I've searched in the
libtool manual, but found no variable that can be used to check if
stdint.h is installed. Maybe the fact that AC_PROG_LIBTOOL does not fail
means that the header file is avalaible. We can also add a check of all
the header files  we need.
