After fiddling with c_defs.h, I was able to get it to compile without  

For those interested, here it is:

/* include/c_defs.h.  Generated by configure.  */

/* File c_defs.h.in is used by configure to generate c_defs.h
    Variables that configure defines should be #undef-ined in
    include/c_defs.h.in !!! */

/* fortran-to-C naming convention, for functions with and without
    underscores in the name (some compilers treat them differently) */

#define F77_FUNC(name,NAME) name
#define F77_FUNC_(name,NAME) name

/* do we have the mallinfo structure (see clib/memstat.c) ? */
