bash-2.05a on HP/UX 10.20

[Alexander Bartolich]

On an old HP/UX machine idling around I compiled bash-2.05a
with HP's cc. The only option of ./configure I used was --prefix.
Compilation would choke on getldouble() in builtins/printf.def
in some code guarded by HAVE_LONG_DOUBLE.
It seems that HP has it's very own idea on this type.

>From /usr/include/stdlib.h:

typedef struct {
   unsigned int word1, word2, word3, word4;
} long_double;

long_double strtold(const char *str, char **ptr);

The expression "long double" is accepted by the compiler,
but seems to have no special meaning. A grep "long.*double"
in /usr/include should only occurences of long_double.

My work-around was to #undef the line regarding
HAVE_LONG_DOUBLE in config.h.
