can not compile ddd-3.2.1 and ddd-3.2.91 on red hat 7.0

[S. Z. Zhou]

Dear All:

I try to install ddd on my RH7.0. I first successfully installed
lesstif-0.91.21.Then
try compile the ddd-3.2.1 and ddd-3.2.91 source;
But both comes following messages:

~/ddd-3.2.91]$
~/ddd-3.2.91]$ gmake
...
...
c++ -DHAVE_CONFIG_H -I. -I. -I. -I./..     -DNDEBUG -O2 -g -W -Wall
-trigraphs  -c LineGESI.C
c++ -DHAVE_CONFIG_H -I. -I. -I. -I./..     -DNDEBUG -O2 -g -W -Wall
-trigraphs  -c PannedGE.C
PannedGE.C: In function `void __static_initialization_and_destruction_0
(int, int)':
PannedGE.C:88: non-lvalue in unary `&'
gmake[1]: *** [PannedGE.o] Error 1
gmake[1]: Leaving directory `/home/zheng/ddd-3.2.91/ddd'
gmake: *** [all-recursive] Error 1
~/ddd-3.2.91]$

Could anybody give me some clues?

Many thanks.
