Subject: [PATCH] Support for NO_OPENSSL
X-Git-Tag: v0.99.3~26
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=dd53c7ab297cc491eb5164198e63d670c7b48530;p=git.git

[PATCH] Support for NO_OPENSSL

Support for completely OpenSSL-less builds. FSF considers distributing GPL
binaries with OpenSSL linked in as a legal problem so this is trouble
e.g. for Debian, or some people might not want to install OpenSSL
anyway. If you

	make NO_OPENSSL=1

you get completely OpenSSL-less build, disabling --merge-order and using
Mozilla's SHA1 implementation.

Ported from Cogito.
