+ Title: DIVIDE BY ZERO
+ Description: This is bug 3468949 on the SourceForge website (submitted by
+ Philipp Klaus Krause):
+ "lib_strtod.c does contain divisions by zero in lines 70 and 96.
+ AFAIK, unlike for Java, division by zero is not a reliable way to
+ get infinity in C. AFAIK compilers are allowed e.g. give a compile-
+ time error, and some, such as sdcc, do. AFAIK, C implementations
+ are not even required to support infinity. In C99 the macro isinf()
+ could replace the first use of division by zero. Unfortunately, the
+ macro INFINITY from math.h probably can't replce the second division
+ by zero, since it will result in a compile-time diagnostic, if the
+ implementation does not support infinity."
