Marius Gerbershagen cb03494a6d ieee_fp: use explicit checks for fpe bits if feenableexcept is not declared 
Using isnan and isfinite to check for floating point exceptions
doesn't work when we want floats to be able to have infinity or NaN as
values, thus this option was removed with commit
5f71f728a3. However, we can still use
fetestexcept to explicitly check if floating point exceptions occurred
even when we can't use the feenableexcept/SIGFPE signal delivery
mechanism.

Previously, we had something like this in the
ECL_MATHERR_TEST/ECL_MATHERR_CLEAR macros, but this was not used
consistently in our codebase (the ECL_MATHERR_TEST macro was missing
in many places). Instead of error-prone testing at every point of
computation, we call fetestexcept in DO_DETECT_FPE when creating a new
float/complex float. In order to avoid having to do this twice, the
DO_DETECT_FPE2 macro is introduced.

A minor disadvantage of this strategy is that floating point
exceptions may be signaled later than they occurred.

README.md

ECL stands for Embeddable Common-Lisp. The ECL project aims to produce an implementation of the Common-Lisp language which complies to the ANSI X3J13 definition of the language.

The term embeddable refers to the fact that ECL includes a Lisp to C compiler, which produces libraries (static or dynamic) that can be called from C programs. Furthermore, ECL can produce standalone executables from Lisp code and can itself be linked to your programs as a shared library. It also features an interpreter for situations when a C compiler isn't available.

ECL supports the operating systems Linux, FreeBSD, NetBSD, DragonFly BSD, OpenBSD, Solaris (at least v. 9), Microsoft Windows (MSVC, MinGW and Cygwin) and OSX, running on top of the Intel, Sparc, Alpha, ARM and PowerPC processors. Porting to other architectures should be rather easy.
