removed usage of unset variables (by a function that does nothing!)

return an int

return an int, not a CURLcode

use CURLcode, not int, prevents picky compilers to warn

the now and start variables were never really used

Ben Greear's SO_BINDTODEVICE patch that binds to a network interface "even
more" when the previous approach. Known to work on Linux, possibly on other
platforms as well.

Tor Arntsen made the ares build warnings etc get included as well

Greg Hewgill found out 'contentlength' wasn't big enough to hold a large file!

make the path const

I made the same fix here, that Tor already did in the ftp.c code. To make
sure this doesn't get weird on 64bit archs.

Tor Arntsen's fix for the bad (64bit wise) typecast when using gmtime()

Make hostcache_fixoffset() take a long for offset, to fully work with 64bit
archs, also no longer typecast pointers to ints as that is a nono on 64bit
systems.

up to date with recent fixes

If no nroff tool is found, or if no command line switch to nroff that converts
a man page to text is found, we disable the built-in manual stuff to still
be able to build.

support configure --disable-manual

added --enable/disable-manual

no need to run make test in the data dir anymore

provide a source path to the servers to make them find the tests when run
outside the source dir, not needing any symlinks

stop doing the weirdo symlinks

removed the subchar variable, it was only set and never used

removed the ldaptext variable, it was only set and never used

removed the nth variable, it was only set and never used anyway

No longer receive the return code in ConnectionKillOne() that wasn't dealt
with anyway and thus caused picky compiler to warn.

Andr�s Garc�a's additional fix to make the OpenSSL stuff work for msys/mingw

#if-check for SIGALRM before assuming it is present
