Solaris 7 compilation error - Mailing list pgsql-ports

Hi,
  I need some help.
I've just tried to compile postgresql source at Solaris and got an error.

Machine:    SparcStation 10 with 64MB.
OS:        Solaris 7
cc:        gcc-2.95-1

postgresql:    I tried both 7.0beta4 and 7.0 and got the same error

I also tried to configure with no additional options and then "--with-tcl
--with-x".

Thanks a lot in advance...
Jirka
