I've noticed that curl_getenv() uses getenv() on Windows[1]. However,
environment variables set with SetEnvironmentVariable() are not seen by
getenv() (although GetEnvironmentVariable() sees changes done by
putenv()), and since SetEnvironmentVariable() is preferable to putenv()
because the former is thread-safe, this can be an issue. At least it
affects thread-safe PHP builds[2].
Is there anything that prevents libcurl to use GetEnvironmentVariable()
instead of getenv()?

Confirmed. I've opened an issue [1] for further discussion.
