So I was right about parser.y.Your Bison parser generator must be
generating an #include <stdlib.h> in y.tab.c, unlike my Bison.

I already commited a fix which eliminates that dependency.

The Bison documentation doesn't provide any guarantee about what
header is adds. The version I have says this:

  In some cases the Bison parser file includes system headers, and in
  those cases your code should respect the identifiers reserved by those
  headers.  On some non-GNU hosts, `<alloca.h>', `<stddef.h>', and
  `<stdlib.h>' are included as needed to declare memory allocators and
  related types.

You may get includes, might not.

Thanks again.
