#  From UPC: Building And Using Static And Shared "C"

# #+begin_QUOTE
# we need that all jump calls ("goto", in assembly speak)
# and subroutine calls will use relative addresses, and not
# absolute addresses. Thus, we need to use ... ~-fPIC~ or
# ~-fpic~
# #+end_QUOTE
#
#  From makepkg.conf
# -march (or -mcpu) builds exclusively for an architecture
# -mtune optimizes for an architecture, but builds for
#  whole processor family

# |- man 7 feature_test_macros
# checks to be performed to detect some buffer overflow
# errors when employing various string and memory
# manipulation functions ... some  conforming programs

# -fcf-protection
# | Info pages for gcc (gnu compiler collection)
# intended to protect against such threats as
# Return-oriented Programming (ROP), and similarly

# Use pipes rather than temporary files for communication

# | Info pages for gcc (code generation conventions)
# leads to more efficient code by eliminating PLT stubs and
