LOTS of failures when making check for gfortran--is it Ok?

LOTS of failures when making check for gfortran--is it Ok?

[sean yang]

I successfully compile a GCC4.0.2 with Fortran front end. I tried to use it 
to compile some fortran programs, so far all of them work fine.

But the make check gave lots of failure. Is it tolerable to have thousands 
of failure?

objgcc-4.0.2>make -k check 1>record.tmp
objgcc-4.0.2>cat record.tmp

No.  You need to look at the log to see what the failures were.

No, this means that something's broken in your build, and the compiler  
is probably not usable.  Nevertheless, you may want to use at least  
gcc 4.1.1, as the gfortran that comes with gcc 4.0.x isn't really  
usable, even if the testsuite passes cleanly.

Regardless of version, testsuite will show unsatisfactory results if 
your build did not complete, for example if you didn't build 
libgfortran.   But you have been ignoring plenty of questions on why you 
are trying to build this broken version, so I expect today's replies to 
be ignored as well.
