Wonderful! Thanks so much. It compiles without a hitch on Intel
and PPC now.
I saw the error in fib_table.h - but to look at that one line and
automatically realize the answer is "make distclean" rather than
something else in the hundreds of source files, configure options or
Apple compiler bugs. I fully realize that to anyone with any
reasonable amount of autotools experience, that's as plain as the nose
on your face.
As a low-knowledge level user of the autotools, I have always
defaulted to "make clean" thinking that "make distclean" was for
package maintainers. I see the error in that thinking now, and had I
thought about it more, I probably would have said "Duh."
However, I may not be alone in such thinking.
Perhaps additional dumb questions could be avoided with something like:
"Error, error, this data is for 64 bits - have you run make distclean
Just a suggestion - thanks again!
