>Description:
The change to MXUNIT in /usr/local/gcc-3.2.1.source/libf2c/libI77/fio.h
from 100 to 10000 doesnt appear to be reflected in the compilation. Compilation tested with the following code.
       program test

       do i = 1,10
          print *, 'Hello world ',i
       end do
       open (unit = 256,file = 'test_file',status='unknown')
       do i=1,10
          write(256,100) i
 100      format (1x, 'Hello world ',i3)
       end do
       stop
       end

here is the output from the compiled code.
 Hello world  1
 Hello world  2
 Hello world  3
 Hello world  4
 Hello world  5
 Hello world  6
 Hello world  7
 Hello world  8
 Hello world  9
 Hello world  10
open: illegal unit number
apparent state: unit 6 (unnamed)
last format: list io
lately writing direct formatted external IO
Abort

I have successful and correct gcc_3.0.2 installations with MXUNIT set to 10000. Code demands 1000 as lu number reflects type of file currently in use not the total number of open files.
