+The patch below fixes a crash building libgfortran on arm-linux-gnueabi.
+
+This target doesn't really have a 128-bit integer type, however it does use 
+TImode to represent the return value of certain special ABI defined library 
+functions. This results in type_for_size(TImode) being called.
+
+Because TImode deosn't correspond to any gfortran integer kind 
+gfc_type_for_size returns NULL and we segfault shortly after.
+
+The patch below fixes this by making gfc_type_for_size handle TImode in the 
+same way as the C frontend.
+
+Tested on x86_64-linux and arm-linux-gnueabi.
+Applied to trunk.
