Paul Moore made curl check for the .curlrc file (_curlrc on windows) on two

more places. First, CURL_HOME is a new environment variable that is used
instead of HOME if it is set, to point out where the default config file
lives. If there's no config file in the dir pointed out by one of the
environment variables, the Windows version will instead check the same
directory the executable curl is located in.
