 	# Python headers may need some -f* flags, leave them in.
 	# We want the sed commands to look like 's/-[WDOm][[:alnum:][:punct:]][[:alnum:][:punct:]]*//g' and 's/-arch [^[:space:]]*//g', but automake eats brackets.

+	# The above sed BRE matches parts of legal options, stipping down part of that option, resulting in invalid gcc arguments. Gentoo Bug #415793
+	# For instance, '-floop-stip-mime' becomes '-floop-strip', and '-fvect-cost-model' becomes '-fvect-cost'.
