# * `-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.
