* m4/gnulib-cache.m4 (gl_MODULES): Add `flock' (provides flock(2)
  declaration and implementation), `fpieee' (fixes floating point
  behavior on Alpha and SH), `stdlib' (provides an unsetenv(3)
  declaration, among others), `putenv' (provides a putenv(3) declaration
  and implementation with the semantics we need).

dnl The include of <stdio.h> is because IBM C 9.0 on AIX 6.1 supports
dnl include_next when used as first preprocessor directive in a file,
dnl but not when preceded by another include directive. Additionally,
dnl with this same compiler, include_next is a no-op when used in a
dnl header file that was included by specifying its absolute file name.
dnl Despite these two bugs, include_next is used in the compiler's
dnl <math.h>. By virtue of the second bug, we need to use include_next
dnl as well in this case.
