problem compiling tcl

when I am trying to compile the ns-allinone2.1b5 on Linux ( with the kernel of 2.2.10 and
egcs 1.1.2), the compiler report the following error:

./../generic/tclPosixStr.c: In function "Tcl-ErrorId"
./../generci/tclPosixStr.c.340: duplicate case value
./../generci/tclPosixStr.c.328: this is the first entry for that value
./../generci/tclPosixStr.c: In function "Tcl_ErrorMsg"
./../generci/tclPosixStr.c.787: duplicate case value
./../generci/tclPosixStr.c.775 this is the first entry for that value
make: *** [tclPosixStr.o] Error 1
tcl8.0.4 make failed! Exiting...

Is anyone who have met this before and happen to know how to solve it?

thanks
