# ANSI Mode
#
# These flags cause GCC to predefine __STRICT_ANSI__. Please be warned
# that Cosmopolitan headers are written to comply with that request if
# it's possible to do so. Consider the following example:
#
# make -j12 -O o//tool/viz/printvideo.i
# clang-format-10 -i o//tool/viz/printvideo.i
# less o//tool/viz/printvideo.i
#
# You'll notice functions like memcpy(), ioctl(), etc. get expanded into
# wild-eyed gnu-style performance hacks. You can turn it off as follows:
#
# make -j12 -O MODE=ansi o/ansi/tool/viz/printvideo.i
# clang-format-10 -i o/ansi/tool/viz/printvideo.i
# less o/ansi/tool/viz/printvideo.i
#
# Here it becomes clear that ANSI mode can help you decouple your source
# from Cosmopolitan, by turning it into plain ordinary textbook C code.
#
# Another potential use case is distributing code to folks using tools
# such as MSVC or XCode. You can run your binary objects through a tool
# like objconv to convert them to COFF or MachO. Then use ANSI mode to
# rollup one header file that'll enable linkage with minimal issues.
