Title: Internal Error building GCC - gcc-2.95.2

Hello,

  I am attempting to install gcc-2.95.2 on a DG-UX system.  During the 'make bootstrap-lean' portion of the build, I received the following internal error:

===============================================================================
dgdcc #  make bootstrap-lean
......
After about 1 hour of building various components of the compiler........

================================================================================

My current compiler:
# gcc -v
Reading specs from /usr/local/lib/gcc-lib/m88k-dg-dguxR4.11MU04/2.8.1/specs
gcc version 2.8.1

My current OS:
 uname -a
dgux dgdcc R4.11MU04 generic AViiON mc88100

My first attempt to build this was with gcc 2.6, I received the same error.  Then I upgraded to gcc 2.8.1 and received the same error.  (Along the way I up graded to gnumake 3.79 in order to successfully configure.)

This same error occurrs if I make with 'bootstrap' and if I choose the 'LANGUAGE=c' only.

If this is not enough information, please let me know, I'll send what you need, asap.  Thanks in advance for any information that you can provide.

    Sincerely,
