[gnu.g++] g++-1.27.0 and SunOS 4.0.1

	Hello, folks!  I'm in the process to get g++-1.34.x but still using
g++-1.27.0 compiled on the sun under SunOS 3.5.  Recently, we upgraded our
SunOS from 3.4 to 4.0.1.  Then, I tried to link the g++ programs with the
linpack library(written in fortran), it failed and produced the following
error:

Undefined symbols:
 Fc_conv_f
 Fc_neg
 Fc_add
 Fc_minus
 Fc_div
 Fc_mult
 Ff_conv_c

However, when I linked on the suns under SunOS 3.4 and 3.5(still we have some),
it worked fine.  Eventually, all of our system will be upgraded to 4.0.1.
  Does anybody give me some advise to avoid this problem?  This doesn't happen
on g++-1.34.x?

Thanks in advance,
