I would suggest to use "cc -E $CFLAGS" instead of "cc -E" during
configure. $CFLAGS might contain some -I flags pointing to include
directories to search for xpm.h or png.h, for example.


What is the actual problem?

The problem was that configure wasn't smart enough to find
xpm.h and some other headers, even though CFLAGS contained
"-I/usr/local/include" pointing to the right directory.
I have no time to test it now, but I would think all of these may work:

  CFLAGS="-O5 -g" ./configure --something
  CC="cc -E -O5 -g" ./configure --something
  ./configure --something CFLAGS="-O5 -g"
  ./configure --something CC="cc -E -O5 -g"
Currently I am using

        export IMLIBCONF=/usr/local/bin/imlib-config
        export GTK_CONFIG=/usr/local/bin/gtk-config
        export CFLAGS=-I/usr/local/include
        export LDFLAGS"=-L/usr/local/lib -R/usr/local/lib"
        export CC="cc $CFLAGS $LDFLAGS"
        export CPP="$CC -E"
        ./configure --prefix=/usr/local/stow/fvwm-2.5.7
        make
Please note that I am _not_ using gcc. Standard gcc looks
in /usr/local/include by default, even if you installed
it somewhere else.
