Paul,

The system I use is the following:

SunOS gradlab.ucsd.edu 5.8 Generic_108528-14 sun4u sparc SUNW,Ultra-60

The compiler is CC:

CC: Sun WorkShop 6 update 1 C++ 5.2 2000/09/11

It  barked  about a badly formed expression on line 71. I have changed
it:

From:
        long double two = long double(2.L);
To:
        long double two = (long double)(2.L);

This compiled and produced the following output:

--------------------------------------------------
long double_significant_digits 36
std::numeric_limits<long double>::digits = 113
pi_l = 3.1415926535897932384626433832795028
pi = 3.1415926535897932384626433832795028
pi_u = 3.14159265358979323846264338327950318
middle is lower limit.
--------------------------------------------------

If  you want to have some additional tests compiled and run, send your
sources to me.

Leo.
