+ * GCC is stated as a dependency. In fact the code is mostly standard C,
+ with C99 initializers, long long and possibly the occasional // comment as
+ the main departures from C89. Additional GCCisms will be accepted if it's
+ impractical to avoid them. At least one active user is still using GCC
+ 2.95, so extensions that only appear in later versions are to be avoided
+ for the time being.
