Has anyone got it working on android devices (arm based platforms)

[GoogleCodeExporter]

Just curious has anyone got miniz working on arm-based Android devices. 

I had a stripped down version of miniz (v115_r4), which contains only 
mz_compress() and mz_uncompress() functions and their dependenices. It is 
working well on a Ubuntu desktop, however, after I ported it to Android, I 
found that if the compress block size is 16K bytes or bigger, the compression 
can easily fail. Most time it failed silently, I only noticed the problem when 
trying to uncompress the compressed the content. 

Confirmed the issue is on the compression side by trying to uncompress the same 
compressed block using miniz on Ubuntu PC, it failed with the same error: 
MZ_DATA_ERROR. Also tried using miniz on Ubuntu PC to compress and uncompress 
the same original data block (16Kbytes), and it works fine.

I will for sure debug further and report back to this thread, just in case 
someone already done the simliar porting work and knows what need to be tweaked 
...

Btw, Rich, very nice tool, thanks a lot for sharing.

Thanks weichence. I'm going to have an android dev environment setup at work 
soon, so I should be able to try reproducing this.

Small information:

it fails line 1463:
if (counter) { TINFL_CR_RETURN_FOREVER(36, TINFL_STATUS_FAILED); }

counter is set to 1 by the line above, where out_buf_size_mask = -1
((out_buf_size_mask + 1) < (size_t)(1U << (8U + (r->m_zhdr0 >> 4))))

Hi Rich:

I got it working, it turned out to be some stupid copy/paste mistake I made 
when trying to further simplify your code.

Got it working now as well. The Keil compiler didn't like the initialization of 
the following array:

tdefl_write_image_to_png_file_in_memory_ex

mz_uint8 pnghdr[41]
