Build errors on 10.10.5

[erco77]

Using current fltk 1.4.x (git commit: debbba1), used the following to build:
./configure --enable-localjpeg --enable-localpng --enable-localzlib ; make clean; make -j 4

Getting these fatal errors building on MacOS Yosemite (10.10.5):

Looks like the first of the warnings was introduced in c720aae.
Then the fatal error was introduced in commit 13e05f4.

This is probably one for @ManoloFLTK

[ManoloFLTK]

@erco77 That should be fixed with 8bbedd6 . Please, close the issue if you confirm.

Confirmed -- builds to completion now -- thanks Manolo!
