[oe] mpfr-native_svn.bb: Problems accessing the repository(s) behind a proxy

[Hauser, Wolfgang (external)]

Hello,

as I am sitting behind an restrictive proxy, I'm unable to use svn:
protocol.

The svn repository used for mpfr-native_svn.bb is accessible via svn: or
https: .
The https: access needs an authentication (--username= --password==)
according to the webpage.

Is there a possibility to send the authentication for SRC_URIs using
https: and ignore the ?
FETCHCOMMAND_SVN ?

Or, how can I pin the mpfr_3.0.0.bb for native stage ?

Regards
