Of course:

  /* Define if you have the <wchar.h> header file.  */
  #define HAVE_WCHAR_H 1

  /* Define if you have the <wctype.h> header file.  */
  #define HAVE_WCTYPE_H 1

  /* Define if you have the btowc function.  */
  /* #undef HAVE_BTOWC */

I believe the problem is

  # if !defined _LIBC
  typedef unsigned long int uintptr_t;
  # endif

in libiberty/regex.c which comes after our #inclusion of
<usr/include/sys/int_types.h> via <usr/include/sys/types.h>.
And int_types.h contains:

  /*
   * intptr_t and uintptr_t are signed and unsigned integer types large enough
   * to hold any data pointer; that is, data pointers can be assigned into or
   * from these integer types without losing precision.
   */
  #if defined(_LP64) || defined(_I32LPx)
  typedef long                    intptr_t;
  typedef unsigned long           uintptr_t;
  #else
  typedef int                     intptr_t;
  typedef unsigned int            uintptr_t;
  #endif

Unconditionally typedef-ing uintptr_t in application code seems rather
problematic to me.
