# Leave in extra flags that produce no warnings (covered by -Wall):
#	-Wimplicit-int -Wreturn-type -Wunused -Wswitch -Wchar-subscripts -Wparentheses
# Leave out extra flags that produce some warnings:
#	-Wtraditional
#	-W -Wuninitialized (covered by -Wall)
# Perhaps also leave out flag that produces extra warnings (Linux, ...?):
#	-Wconversion
# (rotten C crap: value does match prototype, so why this silly 
#  warning "passing arg ... with different width due to prototype" ???
# Perhaps also leave out flag that produces extra warnings (Linux, ...?):
#	-pedantic
# (rotten C crap: prototype matches exactly, so why this silly 
#  warning "promoted argument `c' doesn't match prototype" ???
