gmp-6.2.1 on Tru64 with gcc.

[Jay K]

On OSF/1/Tru64, inttypes.h lacks uint_least32_t and gcc's stdint.h does have uint_least32_t.

autoconf says uint_least32_t is there because it includes stdint.h, but then:

#if HAVE_INTTYPES_H      /* for uint_least32_t */
# include <inttypes.h>
#else                    <== the problem
# if HAVE_STDINT_H
#  include <stdint.h>
# endif
#endif

leading to:

../gmp-impl.h:233:1: error: unknown type name 'uint_least32_t'
In file included from hgcd_appr.c:35:0:
../gmp-impl.h:233:1: error: unknown type name 'uint_least32_t'

So please remove the else?
and then whitespace and comment:
