-$#      locations of the zlib include file zlib.h and the built zlib library,
-$#      zlib.lib.
-$#
-$#   2) If you want to change libpng to a non-standard configuration also
-$#      change the definition of 'awk' in the before rule to the name of your
-$#      awk command.  For more instructions on configuration read
-$#      pngconfig.dfa.
-$#
-$#   3) Delete this file (config.inf).
-<<
- @$(COPY) << pngconfig.dfa
-$# pngconfig.dfa: this file contains configuration options for libpng.
-$# If emtpy the standard configuration will be built.  For this file to be
-$# used a working version of the program 'awk' is required and the program
-$# must be identified in the 'before' rule of the project.
-$#
-$# If you don't already have 'awk', or the version of awk you have seems not
-$# to work, download Brian Kernighan's awk (Brian Kernighan is the author of
-$# awk.)  You can find source code and a built executable (called awk95.exe)
-$# here:
-$#
-$#     http://www.cs.princeton.edu/~bwk/btl.mirror/
-$#
-$# The executable works just fine.
-$#
-$# If build issues errors after a change to pngconfig.dfa you have entered
-$# inconsistent feature requests, or even malformed requests, in
-$# pngconfig.dfa.  The error messages from awk should be comprehensible, but
-$# if not simply go back to the start (nothing but comments in this file) and
-$# enter configuration lines one by one until one produces an error.  (Or, of
-$# course, do the standard binary chop.)
-$#
-$# You need to rebuild everything after a change to pnglibconf.dfa - i.e. you
-$# must do Actions/Mark All Targets for Remake.  This is because the compiler
-$# generated dependency information (as of OpenWatcom 1.9) does not record the
-$# dependency on pnglibconf.h correctly.
-$#
-$# If awk isn't set then this file is bypassed.  If you just want the standard
-$# configuration it is automatically produced from the distributed version
-$# (scripts\pnglibconf.h.prebuilt) by editting PNG_API_RULE to 2 (to force use
-$# of the OpenWatcom library calling convention.)

+$#      locations of the zlib include file zlib.h and the built zlib library,
+$#      zlib.lib.
+$#
+$#   2) If you want to change libpng to a non-standard configuration also
+$#      change the definition of 'awk' in the before rule to the name of your
+$#      awk command.  For more instructions on configuration read
+$#      pngconfig.dfa.
+$#
+$#   3) Delete this file (config.inf).
+<<
+ @$(COPY) << pngconfig.dfa
+$# pngconfig.dfa: this file contains configuration options for libpng.
+$# If emtpy the standard configuration will be built.  For this file to be
+$# used a working version of the program 'awk' is required and the program
+$# must be identified in the 'before' rule of the project.
+$#
+$# If you don't already have 'awk', or the version of awk you have seems not
+$# to work, download Brian Kernighan's awk (Brian Kernighan is the author of
+$# awk.)  You can find source code and a built executable (called awk95.exe)
+$# here:
+$#
+$#     http://www.cs.princeton.edu/~bwk/btl.mirror/
+$#
+$# The executable works just fine.
+$#
+$# If build issues errors after a change to pngconfig.dfa you have entered
+$# inconsistent feature requests, or even malformed requests, in
+$# pngconfig.dfa.  The error messages from awk should be comprehensible, but
+$# if not simply go back to the start (nothing but comments in this file) and
+$# enter configuration lines one by one until one produces an error.  (Or, of
+$# course, do the standard binary chop.)
+$#
+$# You need to rebuild everything after a change to pnglibconf.dfa - i.e. you
+$# must do Actions/Mark All Targets for Remake.  This is because the compiler
+$# generated dependency information (as of OpenWatcom 1.9) does not record the
+$# dependency on pnglibconf.h correctly.
+$#
+$# If awk isn't set then this file is bypassed.  If you just want the standard
+$# configuration it is automatically produced from the distributed version
+$# (scripts\pnglibconf.h.prebuilt) by editting PNG_API_RULE to 2 (to force use
+$# of the OpenWatcom library calling convention.)
