libpng-config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by libpng configure 1.6.43, which was
generated by GNU Autoconf 2.72.  Invocation command line was

$ ../../libpng-1.6.43/configure --enable-static --disable-shared --disable-tests --disable-tools --without-pic --sysconfdir=/zip/etc --datarootdir=/zip/usr/share CFLAGS=-Os CPPFLAGS=-I/root/Dev/Superconfig/cosmos/x86_64/include LDFLAGS=-L/root/Dev/Superconfig/cosmos/x86_64/lib
