You should never give full paths in #include statements.
The search paths for include ('header') files are set by the compiler and
supplemented by -I flags on the command line. If your C compiler is
unable to find <stdlib.h> something is badly wrong, and you need to ask
your 'unix' advisor for help. (BTW, these header files are OS-specific,
and some of them will be compiler-specific -- on my Solaris Unix box cc
and gcc use different versions of some of these headers.)
