Because ELinks is violating a C99 requirement, rather than
something specific to Sun, I don't think it's right to make an
exception for the Sun compiler. Instead, we should make the
functions not inline and measure how that affects the speed.
If it hurts too much, then define e.g. static inline int
inline_elinks_ulongcat() and make both int elinks_ulongcat()
and int elinks_longcat() call that. GCC should generate from
that approximately the same code as from the current sources.
Attached is the modified patch incorporating the above
comments. Please confirm if the patch is acceptable.
Actually I hoped to see some numbers about how much slower
ELinks gets if you just drop the inline specifiers. If the
difference is negligible, then it is better not to complicate
the source code with wrappers.
However I've now looked at C99 6.7.4p3 and it specifically
mentions modifiable objects. So I wonder if we could just put
some const in elinks_ulongcat to make the objects unmodifiable.
