Hello
I'm glad to see that libgd2 is updated to fix the fontconfig related bug.
I aplogized that I have not told that gd_png.c should be modified
when linking with the libpng-1.4, which is current release of the libpng.
The gd_png.c in gd-2.0.36RC1 uses the function png_check_sig in the libpng-1.2
or earlier.
However the png_check_sig is removed from the libpng-1.4.
In the libpng-1.4.1.txt in the libpng-1.4 source from the line 3007,
one finds the following
***********************************
The function
png_check_sig(sig, num)
was replaced with
!png_sig_cmp(sig, 0, num)
It has been deprecated since libpng-0.90.
***********************************
Therefore the patch will below is required for when linking with the libpng-1.4.

}
- if (!png_check_sig (sig, 8)) { /* bad signature */
+ if (png_sig_cmp(sig, 0, 8) != 0) { /* bad signature */
return NULL; /* bad signature */
}
*****************************************
Currently the version of the linpng in cygwin is 1.2 so that png_check_sig does
not cause error.
When the libpng on the cygwin will updated, please apply the above patch and
update libgd.
I wrote the above for your information.
Regards
Tatsuro
