/* On certain systems (such as GNU/Linux), the use of the
INFINITY macro below may generate a warning that can not be
silenced due to a bug in GCC (PR preprocessor/11931). The
preprocessor fails to recognise the __extension__ keyword in
conjunction with the GNU/C99 extension for hexadecimal
floating point constants and will issue a warning when
compiling with -pedantic. */
