#   makefile  (for linux)
#
#   Hand-built -- editable -- simple -- makefile
#
#   For a nodebug version:             make
#   For a debug version:               make DEBUG=yes debug
#   For a shared library version:      make SHARED=yes shared
#   For all versions:                  make all
#   With nonstandard header directories
#                    make EXTRAINCLUDES="-I<nonstandard-incl-dir>"
#
#   To remove all writes to stderr:   add -DNO_CONSOLE_IO to compiler line
#
#   To remove object files in src: make clean
#   To remove object files and executables in prog: make clean
#
#   Customization for I/O with external libraries:
#          jpeg, png, tiff, webp, jp2k, gif
#   Set flags in environ.h.  The default is to have libjpeg, libpng,
#   libtiff and libz, but not libwebp, libopenjp or libgif.
#
#   The functions fmemopen() and open_memstream() conform to
#   IEEE Std 1003.1-2008 ("POSIX.1").  In addition to Linux and BSD,
#   they are supported on macOS (> 10.12), iOS (>= 11.0) and
#   android (sdk >= 23).  However, they are not supported on Windows.
#   The code for determining use of these functions on different platforms
#   is made in environ.h.
#
#   Customization for POSIX-compliant function fstatat().
#   The default is not to use, because some systems do not support it.
#   To use this, #define HAVE_FSTATAT to 1 in environ.h.
#
#   Customization for Cygwin:
#   (1) Use the appropriate $CC
#
#   Compiling under Microsoft Visual Studio
#   (1) Download the vs2000 package.
#   (2) You can also substitute arrayaccess.h.vc for arrayaccess.h, to
#       use the inline macros rather than function calls which are slower.
#
#   To generate function prototypes, you need a program called
#       xtractprotos.  Build it with this command:
#          make xtractprotos
#       Then use it with 'make allheaders'

#     - std=c89 and std=c99 both define __STRICT_ANSI__, which causes
#       the omission of declarations of a number of functions, such
#       as mkstemp, fmemopen, open_memstream, fdopen, etc.  So if you
#       use one of these, also use -U__STRICT_ANSI__.  e.g.,
#          gcc -std=c89 -U__STRICT_ANSI__
#     - std=gnu89 and std=gnu99 do not define __STRICT_ANSI__, so
#       declaration of these other functions is included.
#     - On mingw, it is necessary to use -D__USE_MINGW_ANSI_STDIO.
#       This has no effect on non-mingw systems.
#     - use -Wunused to identify unused variables
#     - use -DNO_CONSOLE_IO to remove all L_INFO, L_WARNING, L_ERROR and
#        ERROR_* logging, and to remove all DEBUG information dependent
#        on whether or not NO_CONSOLE_IO has been defined.
#     - remove -fPIC for Cygwin
