Native build problem with gcc-2.95.2

[Fred Schoen]

Sir or Madam,

After running "Configure" successfully, I have an error during the "make
bootstrap" phase of building native gcc-2.95.2 on platform HP-UX
B.10.20 A 9000/712.  Would you please offer your opinion?  The following
is the segment of the output from "make bootstrap" where the error
occurs:

"Making all in makeinfo
make[3]: Entering directory `/big1/gnu/objdir/texinfo/makeinfo'
gcc -DHAVE_CONFIG_H -I. -I../../../gcc-2.95.2/texinfo/makeinfo -I..

The missing symbol seems to be defined in libiberty/libiberty.a, but
that library is not referenced in gcc-2.95.2/texinfo/makeinfo/Makefile.

Thank you,
Fred.
