a24b08a42a Rename contrib/pngminim/*/makefile.std to makefile 
since there's only one makefile, so users can just type "make"
instead of "make -f makefile.std".

0c062e839d Conditionally compile png_combine_row() and png_read_finish_row() 
which are only used by sequential PNG readers.  This can save some
resources in applications that only do progressive reading.

ee59a9f9f0 Set png_ptr->old_prev_row_size=0 in pngpread.c and pngrutil.c 
This forces the prev_row array to be cleared before the first
row of each image and interlace pass.

e38b432846 Clarified usage of sig_bit as struct vs sig_bit_p as pointer in example.c 
sig_bit was not declared in write_png() and was used differently from
sig_bit in read_png(), as reported by Vincent Torri.  This update changes
sig_bit to sig_bit_p in read_png() and declares sig_bit in write_png().
