AC_CHECK_HEADER by itself does not look for headers, it asks cpp where
they are.  Therefore it is system dependent, and should be extended
using CPPFLAGS.

        CPPFLAGS='-I /my/very/own/include' ./configure

 - Variable: CPPFLAGS
     Header file search directory (`-IDIR') and any other miscellaneous
     options for the C and C++ preprocessors and compilers.  If it is
     not set in the environment when `configure' runs, the default
     value is empty.  `configure' uses this variable when compiling or
     preprocessing programs to test for C and C++ features.
