Hello!

In the beginning of compilation a sed script edits lib/stdint.in.h to become lib/stdint.h. The suspicious lines are:

   76   #if @HAVE_INTTYPES_H@
77 /* In OpenBSD 3.8, <inttypes.h> includes <machine/types.h>, which defines 78 int{8,16,32,64}_t, uint{8,16,32,64}_t and __BIT_TYPES_DEFINED__.
   79        <inttypes.h> also defines intptr_t and uintptr_t.  */
   80   # include <inttypes.h>
   81   #elif @HAVE_SYS_INTTYPES_H@
82 /* Solaris 7 <sys/inttypes.h> has the types except the *_fast*_t types, and 83 the macros except for *_FAST*_*, INTPTR_MIN, PTRDIFF_MIN, PTRDIFF_MAX. */
   84   # include <sys/inttypes.h>
   85   #endif
   86   
   87   #if @HAVE_SYS_BITYPES_H@ && ! defined __BIT_TYPES_DEFINED__
88 /* Linux libc4 >= 4.6.7 and libc5 have a <sys/bitypes.h> that defines 89 int{8,16,32,64}_t and __BIT_TYPES_DEFINED__. In libc5 >= 5.2.2 it is
   90        included by <sys/types.h>.  */
   91   # include <sys/bitypes.h>
   92   #endif

And since @HAVE_SYS_BITYPES_H@ is changed to an empty string the lines become invalid in lib/stdint.h:

   77   #if 1
78 /* In OpenBSD 3.8, <inttypes.h> includes <machine/types.h>, which defines 79 int{8,16,32,64}_t, uint{8,16,32,64}_t and __BIT_TYPES_DEFINED__.
   80        <inttypes.h> also defines intptr_t and uintptr_t.  */
   81   # include <inttypes.h>
   82   #elif
83 /* Solaris 7 <sys/inttypes.h> has the types except the *_fast*_t types, and 84 the macros except for *_FAST*_*, INTPTR_MIN, PTRDIFF_MIN, PTRDIFF_MAX. */
   85   # include <sys/inttypes.h>
   86   #endif
   87   
   88   #if  && ! defined __BIT_TYPES_DEFINED__
89 /* Linux libc4 >= 4.6.7 and libc5 have a <sys/bitypes.h> that defines 90 int{8,16,32,64}_t and __BIT_TYPES_DEFINED__. In libc5 >= 5.2.2 it is
   91        included by <sys/types.h>.  */
   92   # include <sys/bitypes.h>
   93   #endif

This error exists since 30 h (an update yesterday let the NS variant compile but not the X client):

        Compilation exited abnormally with code 2 at Mon Apr  4 21:12:43

I think the code was OK until revno: 103797.


Mac OS X 10.5.8, PPC; GCC 4.5.2; revno: 103819.

If it does exist, it's out of date.
