Compile time error: bash 4.1 on HP-UX 11.31

[Crowe, Edward]

Hello,
        I was trying to compile bash 4.1 for HP-UX 11.31 on Itanium with
HP's compiler (version: "(Bundled) cc: HP C/aC++ B3910B A.06.12 [Oct 11
2006]"). I ran ./configure without options and ran into the following
error.

(Bundled) cc: warning 922: "-g" is unsupported in the bundled compiler,
ignored.
"./printf.def", line 175: error #2147: declaration is incompatible with
          "int vsnprintf(char *, size_t, const char *, __va_list)"
(declared
          at line 693 of "/usr/include/stdio.h")
  extern int vsnprintf __P((char *, size_t, const char *, ...))
__attribute__((__format__ (printf, 3, 4)));
             ^

1 error detected in the compilation of "printf.c".
*** Error exit code 1

Stop.
*** Error exit code 1

Stop.

I looked at builtins/printf.def, and since the vsnprintf definition
seemed optional in the #if/#endif, I commented it out like so:

/*#if !HAVE_VSNPRINTF
extern int vsnprintf __P((char *, size_t, const char *, ...))
__attribute__((__format__ (printf, 3, 4)));
#endif
*/

I re-ran make and it compiled without errors, and the resulting binary
seems to work just fine. Although, I haven't had time to test it too
much yet. Here's the diff:

# diff builtins/printf.def.original builtins/printf.def
174c174
< #if !HAVE_VSNPRINTF
---
> /*#if !HAVE_VSNPRINTF
176a177
> */

Thanks for all the great work!
