0.56: build failure against curl-8.11.0

[0-wiz-0]

When compiling the latest release, 0.56, against curl-8.11.0, there are many deprecation warnings, but also some errors that break the build:

In file included from Curl.xs:34:
const-defenums-h.inc:3056:24: error: 'CURL_STRICTER' undeclared (first use in this function)

I think it is because of

#define CURL_STRICTER /* not used since 8.11.0 */

in curl.h. It used to work with

#define CURL_STRICTER

I think Net::Curl's Makefile.PL can't handle the comment.

Good idea, thanks, @mauke .

I get it to compile, there are still lots of deprecation warnings, and then the self tests hang for me after writing
