I'm NOT rejecting this request, but I am closing it with the intention to follow up with https://github.com/pnggroup/libpng/pull/405
Added optimized RISC-V Vector functions
Windows Universal build
This was fixed in libpng-1.6.38, albeit in a different manner, following on the changes made in the Vcpkg port of libpng.
Support for Digital Mars Compiler (DMC)
I will accept external contributions to support any compiler, but I am closing this request as WONTFIX. Moving on with the libpng development, our interest in a compiler that does not support C99 is very low.

scripts/makefile.gcc does not handle "install"
