This section contains some information about how various compilers work
with this library. It is not comprehensive and updated experiences are
always welcome. Some effort has been made to suppress unhelpful warnings
but it is difficult to achieve this on all systems.

Long double support has been disabled because the native long
double C standard library functions really only forward to the
double versions. This can result in unpredictable behaviour when
using the long double overloads: for example <code class="computeroutput"><span class="identifier">sqrtl</span></code>
applied to a finite value, can result in an infinite result.

Some functions still fail to compile, there are no known workarounds

Long double support has been disabled with these compiler releases
because calling the standard library long double math functions
can result in a segfault. The issue is Linux distribution and
glibc version specific and is Intel bug report #409291. Fully
up to date releases of Intel 9.1 (post version l_cc_c_9.1.046)
shouldn't have this problem. If you need long double support
with this compiler, then comment out the define of BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS
at line 55 of <a href="../../../../../../../boost/math/tools/config.hpp" target="_top">boost/math/tools/config.hpp</a>.

Long double support has been disabled on this platform due to

It should be possible to make this work if someone is prepared
to offer assistance.

the bug effects the test code, not fpclassify itself. The IBM

- the default acceptable error tolerances are quite tight, especially for
long double types with an extended exponent range (these cause more extreme
test cases to be executed for some functions). You will need to cast an
eye over the output from the failing tests and make a judgement as to whether
the error rates are acceptable or not.
