Compilation Issues With Sun Studio 11

[Brian Schubert]

Hello,

I'm having problems compiling Octave 3.0.1 using Sun Studio 11 on
Solaris 9. My current problem is with ov-intx.h:

CC -c -I/usr/local/include -I/usr/local/include/readline
-I/usr/local/include/ncurses -I/usr/local/include -KPIC -I. -I..
-I../liboctave -I../src -I../libcruft/misc  -DHAVE_CONFIG_H   -g
bitfcns.cc -o pic/bitfcns.o

Results in:

Compilation aborted, too many Error messages.

It seems to me that the compiler cannot determine what type "scalar" is
and thus cannot determine the proper function to use. As an experiment,
I cast "scalar" to a "double" on all the lines that produced the errors
and compilation actually succeeded, so it seems that my theory is likely
at lest partially correct (I know very little about C++, however).
Anyway, I would be grateful if anyone could suggest to me a more proper
way with which I may avoid these errors.

Thanks,
