--- Comment #9 from John David Anglin <danglin at gcc dot gnu.org> ---
I don't have a 11.31 system, so you will probably have to work out and test the
fix.

The hpux_long_double hack does two things.  It comments out the _LONG_DOUBLE
define and changes "long_double" to "long double".

Steve Ellcey disabled it for 11.31 and added the hpux_long_double_2 hack
for 11.31.

>From the build error, it looks like 11.31 needs a hack to change "long_double"
to "long double".

It would help to see the uses of long_double in stdlib.h.
