Good news: the Debian hppa autobuilder compiled successfully version
3.1.52-5 of the ocave3.1 package [1].  Just for the record, this
architecture has:

checking for long double... yes
checking size of long double... 8

which means that OCTAVE_INT_USE_LONG_DOUBLE is undefined.  Compilation of
oct-inttypes.cc just issues some warnings:

-DHAVE_CONFIG_H -I/usr/include/freetype2 -Wall -W -Wshadow -Wold-style-cast -O2
