/* On some 32 bit platforms, there is a gcc bug that makes floating point
49+
* calculations and comparisons unstable (see the link below). The problem
50+
* originates in FPU 80 bits registers where double values are not truncated
51+
* to 64 bit values. When gcc compiles some code with enabled optimizations,
52+
* the intermediate results may be kept in the FPU registers without truncation
53+
* to 64 bit values. Extra bits may produce unstable results when comparing
54+
* the numbers.
55+
*
56+
* The generic solution is to save the intermediate results in the memory where
57+
* the values are truncated to 64 bit values. It affects the performance but
58+
* makes the tests stable on all platforms.
59+
*
60+
* PGSPHERE_FLOAT_STORE macro enables storing of intermediate results for FPxx
61+
* operations in the memory. It is enabled by default for 32 bit platforms.
62+
* It can be explicitly enabled or disabled in CFLAGS. To enable it for all
63+
* code the gcc option -ffloat-store may be used as well.
64+
*
65+
* Link to gcc bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=323
