huge number of gfortran testsuite failures

[Jack Howarth]

   Is anyone else having problems with gcc 4.1 branch on MacOS X 10.4?
I find that there are a huge number (> 3000) failures in the gfortran
testsuite. Also when I try to build the fcvs21_f95 NIST tests I get
errors of the form...

./driver_run: line 73: ./a.out: No such file or directory
Process FM019
/usr/bin/ld: Undefined symbols:
___gthrw_pthread_mutex_lock
___gthrw_pthread_mutex_trylock
___gthrw_pthread_mutex_unlock
collect2: ld returned 1 exit status

This was from a svn checkout of tonight's 4.1 branch.
