&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& HPUX

 To compile on HPUX type:

	% make hpux

 and then

	% make install

 after having properly set the LIBDIR variable in the master Makefile.
 The math library is fairly incomplete on HPUX. An extra file
 extramath.c defines basic math functions such as sinh. The precision
 on these functions  is not good, precisely because math function
 log1p is missing. I wonder why the minimal BSD math library is
 not on these machines...

 I've been reported some memory alignment problems on HP750.
 The problem is that simple commands like

 fudgit> let x=2

 leads to a program crash due to a bus error. To get around this
 problem, define DALIGN in src/Makefile.hpux. This forces the code to
 use bcopy() to transfer doubles on a string of int (pointers) while
 reading and writing. The resulting code is slightly slower, but
 stable.

 Some flavors of HPUX need -lmalloc some don't. If it complains about
 not being able to find malloc library just comment it in or out in
 src/Makefile.hpux.

 The math library uses HUGE instead of Infinity and does not have NaN
 values in conjunction with error flags. Since I have only remote access
 to HPUX, parts or src/math.c:errorcheck() should be rewritten (#ifdef
 HPUX) to account for this peculiar behavior. Anybody interested?

 HPUX does not support dynamic loading.

 The ansi version of Fudgit has been tested on HPUX 8.07. Some fiddling
 might be required to comply with other (too many) versions.
