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 -- * Dipl.-Math. Jürgen Hunold ! Ingenieurgesellschaft für * voice: ++49 511 262926 57 !
