# The optimisation options here might seem like micro-management (see gb_COMPILEROPTFLAGS := -O2 -Oy-
# http://www.ffuts.org/blog/dont-spend-time-micromanaging-optimization-options-in-visual-c/
# ), and the exact rationale for this selection of options for
# gb_COMPILEROPTFLAGS is probably lost in history. We used -Ob1 -Oxs
# -Oy- already in OOo 3.2 at least.
# Anyway, changing it to just -O2 broke unit tests. So there must be
# some reason for this particular choice. And if you want to change it
# to something simpler, please run a full make check;)
