There is signal function but the only defined signals are:

SIGINT, SIGILL, SIGFPE, SIGSEGV, SIGTERM, SIGBREAK and SIGABRT.

So we may have to change:

#ifdef HAVE_SIGACTION

to

#if defined(HAVE_SIGACTION) && defined(SIGALRM)

The configure script also needs some help with openssl for Windows, I
have attached a patch for that.

With it, and some extra handholding, I managed to make it compile, it even
works:

$ ./curl -V
curl 7.11.1-20040210 (i686-pc-mingw32) libcurl/7.11.1-20040210
OpenSSL/0.9.7b zlib/1.2.1
Protocols: ftp gopher telnet dict ldap http file https ftps
Features: SSL libz NTLM

Haven't tested it much but things like curl -k https://www.paypal.com work

Unfortunately, that 'curl' is the wrapper script made by libtool and it
doesn't seem to able to change it into the real 'curl.exe'
