The steps above do that. # # Note that it does a sed hack to manually select the compiler, as opposed # to using libpng's configure script, because the latter will choose "gcc" # and produce binaries that depend on cygwin1.dll. # # Also note that the example instructions above builds a specific version of # libpng, which might be different from the headers shipped by Cygwin. As # of 2023-02-07, Cygwin is using 1.6.37 headers, which is about 2 years # behind 1.6.39, but the differences appear to be trivial.
