egcs1.0.3a test case failures on i686-pc-linux-gnu

[Paul Kersting <paul at kwconsulting dot com>]

Sorry about previous unsuccessful postings.  For some reason, my notes
have been truncated, but I'm going to try again.

I am trying to install egcs 1.0.3a on my system (results of config.guess are i686-pc-linux-gnu).  Am using binutils-2.9.1-1.  I did

mkdir objdir
cd objdir
srcdir/configure --prefix /usr/local/egcs
make bootstrap
make -k check

The results of the testsuite indicated the following:
 

  === gcc Summary ===

# of expected passes  4882
# of unexpected failures 1
# of expected failures  5
# of unsupported tests  7
Executing on host: /usr/egcs/gcc/xgcc -v

/usr/egcs/gcc/xgcc version egcs-2.90.29 980515 (egcs-1.0.3 release)

The unexpected failure appears to be in egcs-1.0.3a/gcc/testsuite/gcc.c-torture/special/921210-1.c , based on the following excerpt from gcc.log.

In the test cases for g++, I get:

The unexpected failure appears to be in g++.mike/p6610a.C based on the following excerpt from g++.log:

In the g77 test cases I get

The failures appear to be in  g77.f-torture/execute/dnrm2.f, based on the following excerpt from g77.log:

My primary purpose in installing egcs is to access the g77 compiler, though I would like to use gcc and g++ as well.  I'm a newbie at this, and am at a loss as to what to do next.  Can anyone give me some help with regard to how serious these errors are and what I can do to eliminate them.  I'm reluctant to proceed without understanding this better.

TIA, and again, sorry for prior truncated postings.  I hope this note makes it to the list.
