I needed to bump local curl build version to fix a (php-unrelated) SEGV.  Currently, I have

	curl -V
		curl 7.67.1-DEV (x86_64-pc-linux-gnu) libcurl/7.67.1-DEV OpenSSL/1.1.1d zlib/1.2.11 brotli/1.0.7 libidn2/2.2.0 libpsl/0.21.0 (+libidn2/2.2.0) libssh2/1.9.0_DEV nghttp2/1.40.0-DEV
		Release-Date: [unreleased]
		Protocols: dict file ftp ftps http https imap imaps pop3 pop3s scp sftp smtp smtps tftp
		Features: AsynchDNS brotli HTTP2 HTTPS-proxy IDN IPv6 Largefile libz Metalink NTLM NTLM_WB PSL SSL TLS-SRP UnixSockets

Rebuilding my usual PHP7.3/git install,
(add'l note: fwiw, the following issue also occurs with 7.4/git ...)

	cd php7

	git branch -a | grep \*
		* PHP-7.3

	git log | head
		commit 9083e178f656878cab46aee52b555346ef92a768
		Author: Dmitry Stogov <dmitry@zend.com>

		    Fixed wrong constant usage

works nicely as usual,

But curl extension now fails,

	ext/curl/interface.c:778:25: error: ‘CURLE_OBSOLETE20’ undeclared (first use in this function); did you mean ‘CURLE_OBSOLETE50’?
			  778 |  REGISTER_CURL_CONSTANT(CURLE_FTP_WRITE_ERROR);


Before making noise about in @bugs, wanted to check 1st; known issue? additional/new config req'd?

Here's more detail

A problem on my end, or a bug with new(er) curl/libcurl 'vs' php ext/curl?

If more info's needed b4 redirecting, or to deal with here, pls let me know.

thx!
