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

	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 \*

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!

That appears to be due to a recent change in libcurl[1]. We'll have to
work around that, but I'm not sure how. Define both constants for BC?

It looks like last time this happened (value 16 reused for HTTP2), the
removed constant was reintroduced in curl to avoid just this scenario:
https://github.com/curl/curl/pull/106

Perhaps a patch should be submitted to do the same thing again this time?

which includes the reworked fix for this issue,

now just a matter of the fix making it into next curl release.
