# This option is specific to this configuration; it adds a #define to the
|
|
# generated pnglibconf.h which turns on the (not portable) timing option for
|
|
# pngcp. Note that any option is automatically preceded by PNG_; there is no
|
|
# way round this and this is deliberate.

# Because of the everything off above the option must also be turned on. This
|
|
# may not be done in one step because it is safer and avoids mis-spelled options
|
|
# in user .dfa files to error out if an unrecognized option is turned on.
