---------------------------------------+------------------------------------
 After upgrading transfig, I found out that fig2dev did not work anymore.
 After doing some checking, I found out that the build of transfig fails,
 but that the build script does not detect the error exit status.

 The build fails at the following point:

  genibmgl.c:575:29: error: non-void function 'set_width' should return a
 value [-Wreturn-type]
     if (w == current_width) return;

 I have attached the debug log.
