Can not be used as drop-in replacement for zlib with libpng #36

Open GoogleCodeExporter opened 8 years ago

What steps will reproduce the problem?
1. Make libpng use miniz instead of zlib, by compiling miniz as a static 
library, modifying the libpng makefile to use the compiled library instead of 
zlib, and creating a header file out of miniz.c, to impersonate the original 
zlib.h.

What is the expected output? What do you see instead?
libpng can't be compiled - linker complains about missing inflateReset and 
inflateReset2.

What version of the product are you using? On what operating system?
miniz v115_r4 and libpng-1.6.12 cross-compiling for a custom SuperH target with 
gcc 4.8.2. The cross-compiling setup is tested and works fine.

Please provide any additional information below.

Seems to be a problem similar to issue #16, except here it's not a macro that's 
missing, but two zlib functions that have no equivalents on miniz.
This is especially disappointing because the project homepage claims it is 
tested as a drop-in replacement for zlib, and mentions libpng as an example.
