BUG: gsl-0.4.1/randist/discrete.c typename stack_t conflict on HP

[Frederick W. Wheeler]

Hello,

I don't subscribe to gsl-discuss@sourceware.cygnus.com, so please
contact me directly if there are any questions of comments regarding
this report.

% uname -a
HP-UX hpw5 B.10.20 A 9000/780 unknown
% gcc --version
egcs-2.91.66

I just tried to compile gsl-0.4.1 on this machine using:

configure \
  --prefix=/home/wheeler/usr/stow//gsl-0.4.1 \
  --exec-prefix=/home/wheeler/usr/stow//gsl-0.4.1/hppa1.1-hp-hpux10.20
make

I got this compilation error:

Making all in randist
make[2]: Entering directory `/tmp/build-hppa1.1-hp-hpux10.20-gsl-0.4.1/gsl-0.4.1/randist'

discrete.c:141: conflicting types for `stack_t'
/usr/include/sys/newsig.h:50: previous declaration of `stack_t'

Perhaps stack_t should be changed to gsl_stack_t in discrete.c?

I was not able to figure out the sequence of includes that led to
sys/newsig.h.

gsl compiled perfectly for me on a Solaris 2.6 machine.

Thanks,
Fred Wheeler
