Remove slash/backslash problem, now only slashes are used,
Wmake automaticaly translate slash/backslash to proper version or tools are not sensitive for it.
Enable spaces in path.
Use internal rm command for all host platforms
Add error message if old Open Watcom version is used. Some old versions exhibit build problems for Curl latest version. Now only versions 1.8, 1.9 and 2.O beta are supported

Remove compilation message for platforms where size of long type
is equal size of int type.

Ensure a source file isn't generated for the following informational
command line parameters when --libcurl is specified:

--help, --manual, --version and --engine list

As the output would only include a fairly empty looking main() function
and a call to curl_easy_init() and curl_easy_cleanup() when performed
with --engine list.

Correctly output libcurl source code that includes multiply operations
as specified by --next. Note that each operation evaluates to a single
curl_easy_perform() in source code form.

Also note that the output could be optimised a little so global config
options are only output once rather than per operation as is presently
the case.

incompatible types - from 'OperationConfig *' to 'GlobalConfig *'

For HTTP/2, we may read up everything including responde body with
header fields in Curl_http_readwrite_headers. If no content-length is
provided, curl waits for the connection close, which we emulate it
using conn->proto.httpc.closed = TRUE. The thing is if we read
everything, then http2_recv won't be called and we cannot signal the
HTTP/2 stream has closed. As a workaround, we return nonzero from
data_pending to call http2_recv.

nghttp2 has yet again extended its callback struct and this is an
attempt to make curl compile with nghttp2 from current git

Other global options such as --libcurl, --trace and --verbose to
follow.

In order to ease the moving of global options such as the error stream,
updated the OperationConfig structure to point to the GlobalConfig.

In addition to adding support for URL specific options via the command
line with --next it is now possible to specify "next" in .curlrc.

Follow up to commit 1a9b58fc to replace the : command line option
with --next and -:.

Added initial support for --next/-: which will be used to replace the
rather confusing : command line operation what was used for the URL
specific options prototype.

A recent change seems to have slightly changed the call stack
produced by the gcc optimizer.

darwinssl: don't omit CN verification when an IP address is used

Change "==" to "=" to honor POSIX test construction.

...and added the HTTP suffix as these options are only used for HTTP2
based connections.

Other global options such as --libcurl, --trace and --verbose to
follow.

In preparation for parsing global options added the GlobalConfig
structure to the getparameter() function.

Original commit message was:
 Don't omit CN verification in SChannel when an IP address is used.

Side-effect of this change:
 SChannel and CryptoAPI do not support the iPAddress subjectAltName
 according to RFC 2818. If present, SChannel will first compare the
 IP address to the dNSName subjectAltNames and then fallback to the
 most specific Common Name in the Subject field of the certificate.

 This means that after this change curl will not connect to SSL/TLS
 hosts as long as the IP address is not specified in the SAN or CN
 of the server certificate or the verifyhost option is disabled.

Compilation was not possible if manuel is disabled due this error:
 error: macro "hugehelp" passed 1 arguments, but takes just 0
  void hugehelp(void) {}
