Expected Behaviour

Software with 'optional' feature disabled should build successfully.

Actual Behaviour

Building with ./autogen.sh && ./configure --disable-png && make -j causes unexpected build failures.

git clone https://github.com/fvwmorg/fvwm3.git
cd fvwm3
./autogen.sh && ./configure --disable-png && make -j
