Dear SL Users,

I have a (perhaps stupid) question. Some time ago I switched to SL 5.0 
(from various SuSE distributions).

Now I've run into a problem with the compatibility of g77. On our 
workstations we have SuSE (guess who's the sys admin ;-)) with

gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)

On my laptop and on other machines in our institute, I have SL with

gcc version 3.4.6 20060404 (Red Hat 3.4.6-3)

In 99.9% of all cases there is no problem with my (rather simple) codes. 
I can compile them without trouble. Only when I do some (either very 
simple) I/O, an incompatibility occurs. It happens if I write to a file 
and then read in the same file again within the same program. This 
worked without trouble in the older gcc version, but creates weird 
run-time errors in the new version:

invalid number: incomprehensible list input
apparent state: unit 1 named RW-total-tadmix4pi-6pi-om-phi-DY.dat
last format: list io
lately reading sequential formatted external IO
Aborted

Here, "RW-total-tadmix4pi-6pi-om-phi-DY.dat" is the file I write to disk 
and then read it in again.

Of course it's not a big deal to rewrite the code that this is 
re-reading not necessary. But, if someone knows a compiler switch or 
the like so that the writing out and reading in of a file in the same 
program works again, it would save me some time.

Cheers,
Hendrik.
