[Bug fortran/24391] New: libgfortran assumes system has int8_t

["bugzilla-gcc at thewrittenword dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Tru64 UNIX 4.0D does not have <stdint.h> or <inttypes.h>. So, it has no int8_t,
int16_t, int32_t, ...

Because of this, the following problem occurred:

...

libgfortran/libgfortran.h tries to handle this case:
  #if !defined(HAVE_STDINT_H) && !defined(HAVE_INTTYPES_H) &&
defined(TARGET_ILP32)
  typedef char int8_t;
  typedef short int16_t;
  typedef int int32_t;
  typedef long long int64_t;
  typedef unsigned char uint8_t;
  typedef unsigned short uint16_t;
  typedef unsigned int uint32_t;
  typedef unsigned long long uint64_t;
  #endif

TARGET_ILP32 is not defined for Tru64 UNIX 4.0D. Rather than the above, why do
you use autoconf tests to determine if the above are true and then add them to
config.h if not?
