Older gcc versions apparently check formal parameters names in function declarations (as well as definitions) to see if they match a name in the global namespace. Revised PNG_EXPORTA macro to not use an empty parameter, to accommodate the old VisualC++ preprocessor. Turned on interlace handling in png_read_png(). Fixed gcc pendantic warnings. Handle longjmp in Cygwin. Fixed png_get_current_row_number() in the interlaced case. Cleaned up ALPHA flags and transformations. Implemented expansion to 16 bits. Version 1.5.2beta02 [February 19, 2011] Fixed mistake in the descriptions of user read_transform and write_transform function prototypes in the manual. The row_info struct is png_row_infop. Reverted png_get_current_row_number() to previous (1.5.2beta01) behavior. Corrected png_get_current_row_number documentation Fixed the read/write row callback documentation. This documents the current behavior, where the callback is called after every row with information pertaining to the next row. Version 1.5.2beta03 [March 3, 2011] Fixed scripts/makefile.vcwin32 Updated contrib/pngsuite/README to add the word "modify". Define PNG_ALLOCATED to blank when _MSC_VER<1300. Version 1.5.2beta04 [March 6, 2011] Define remaining attributes to blank when MSC_VER<1300.
