Hi,

please find a patch removing a clang warning from gregorian _calendar.ipp.

The warning is 
warning: equality comparison with extraneous parentheses [-Wparentheses]
note: use '=' to turn this equality comparison into an assignment
note: remove extraneous parentheses around the comparison to silence this 
warning

The right fix is to remove the extra parentheses.
See the patch for further details. 

Okay to commit?

Yours,

Jürgen
