Compilation error message:

src/Fl_SVG_Image.cxx:80:21: error: out-of-line definition of 'gzopen64' does
not match any declaration in 'Fl_SVG_Image'; did you mean 'gzopen'?
void* Fl_SVG_Image::gzopen(const char *fname) {
                    ^~~~~~
                    gzopen
/usr/include/zlib.h:1709:20: note: expanded from macro 'gzopen'
#    define gzopen gzopen64
                   ^

The culprit was the macro defined in zlib.h (above).
