SCO 5.0.7 Installing gcc 3.4.3 cause error in make

Did anyone get gcc updated on sco 5.0.7 ?

Here is what I did

installed Openserver Development System
installed Openserver Linker and Application Development Libraries

This gave me older gcc compiler 2.95.3 which is required to compile the latest gcc 3.4.3
Configuration went ok but issued a 'make bootstrap' command it bumped into this

    cc -c  -g -DHAVE\_CONFIG_H  -I. -I../../src/gcc-3.4.3/intl ../../src/gcc-

3.4.3/intl/localealias.c
UX:i386acomp: ERROR: "../../src/gcc-3.4.3/intl/localealias.c", line 164: error:
