#
# * `-fno-strict-aliasing` since it's almost impossible to write a memory
#   manager without breaking C's aliasing rules. Better be on a safe side.
#   Nice post about these things: http://blog.regehr.org/archives/1307
#
# * `-Wno-strict-aliasing` to turn of warnings about breaking aliasing rules. 
#   While one would think these wanings should be turned off when 
#   `-fno-strict-aliasing` is passed, apparently some GCCs bark anyway. 
#
# * `-fno-stack-protector` is (was) required on Ubuntu brands where it's 
#   by default on. Smalltalk/X green thread implementation does not wotk
#   well with it. 
#
# * `-U_FORTIFY_SOURCE` is (was) required on Gentoo as a workaround for failing 
#   longjmp check when _FORTIFY_SOURCE is defined (which is enabled by default 
#   on Gentoo. Remove when fixed.
