Subject: Remove the likely/unlikely macros.
X-Git-Tag: v0.4.0~50^2~1
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=f06808fd0c3890b4a9674efc708ccd9907225f53;hp=36d1c3d162c687cd11c05e88a93fa1de78f06eab

Remove the likely/unlikely macros.

These also slow down the compress filter, its only user, by about 10%.
