help with install on solaris8

[Jeff Maley <jmaley@xxxxxxxxxxxxxx>]

i am not sure if this forum is for help, but i am having problems installing this on solaris 8. when trying to compile either 1.0.0 or 1.1.0, i get:

# make
/usr/local/bin/gcc -O2 -Wall -I/usr/X/include -o rdesktop.o -c rdesktop.c
/usr/ccs/bin/as: "/var/tmp/ccth8uCS.s", line 514: error: unknown opcode ".subsection"
/usr/ccs/bin/as: "/var/tmp/ccth8uCS.s", line 514: error: statement syntax
/usr/ccs/bin/as: "/var/tmp/ccth8uCS.s", line 572: error: unknown opcode ".previous"
/usr/ccs/bin/as: "/var/tmp/ccth8uCS.s", line 572: error: statement syntax
make: *** [rdesktop.o] Error 1


do i need a specific lib or am i doing something wrong?

# uname -a
SunOS guru 5.8 Generic sun4u sparc SUNW,Ultra-5_10

thanks in advance.
