These kinds of interleaved conditionals make me nervous that we'll get
something wrong (especially without braces, it's not immediately clear
that both sides are a single statement).
I wonder if it would be more readable to do something like:
#if LIBCURL_VERSION_NUM < 0x070c00
static const char *curl_easy_strerror(CURL *curl)
{
return "[error code unavailable; curl version too old]";
}
#endif
Then callers don't have to individually deal with the ifdef. It does
mean that the user sees that kind-of ugly message, but maybe that is a
good thing. They know they need to upgrade curl to see more details.
