To expand on Yaakov's answer, yes -- this is intended.  The libpng API 
changes with each major release, which is why the DLL name gets "bumped" 
in each case.  libpng14-1.4.x-y provides cygpng14-14.dll, while 
libpng12-1.2.x-y provided cygpng12.dll.

FWIW, the png team has abandoned even/odd numbering to designate 
stable/development releases. Hence, the 1.5.x series is now the 
"current" stable release -- our "new" libpng-1.4.x is already obsolete. 
I'll publish libpng15 before Christmas (by which time, of course, 
libpng-1.6 will be stable).
