That is really '''excellent''' news. Is there any chance either you or I
could check this with the Sun compiler on Solaris, before you make an
official release? The Sun compilers more fussy than gcc, but would give us
a performance boost on Solaris.
The fact the compiler is more fussy, also tends to weed out some sort of
bugs. On 't2' the Sun C compiler is
{{{/opt/sunstudio12.1/bin/cc}}}
and the C++ compiler is
{{{/opt/sunstudio12.1/bin/CC}}}
On the C++ compiler, you will probably need the option
{{{
-library=stlport4
}}}
as that will then implement the latest C++ standard. (The older C++
standard is not compatible with the latest standard. For backwards
compatibility Sun's C++ compiler defaults to the old C++ standard.}}}
Previously I tried building lcalc with the Sun compiler but got lots of
warnings and error messages. But if the code has been cleaned up, things
have more chance of working.
The point I made above about storing the exact (or least high precision)
result in the test file, would be that is some record of what and should
be, even though it is not going to be achieved.
Then if you bring out a later version of lcalc, which deviates more from
the exact result, people will at least know. It would only add 70 or so
bytes to a file.
