curl_socket_t is unsigned (like Windows) that could cause it to wrongly

CURLOPT_MAX_RECV_SPEED_LARGE that limit tha maximum rate libcurl is allowed
to send or receive data. This kind of adds the the command line tool's

and -F, which it didn't before.

ares_dns.h, which break c-ares on my Sparc64. Bit-wise operations in C
operate on logical values. And in any event the octets are already in
big-endian (aka network) byte order so they're being reversed (thus the
source of the breakage).

UDP even when a poll(2) or select(2) suggest otherwise.

of how to write such a file

-fvisibility=hidden on gcc >= 4.0.  This reduces the size of the libcurl
binary and speeds up dynamic linking by hiding all the internal symbols from
the symbol table.

trying to maintain an accurate list in this file (too).

variables, simplified the splayprint function, modified
Curl_splayremovebyaddr() to return error code. All in an effort to track down
the reported splay problem, but I've failed to do that so far...

more similar to other configure builds (== use .la for libext and no binext)

transformed.
