I used your second option with the batch file as follows:
- I renamed gfortran.exe to gfortran4.0.0.exe
- I put a one-line batch file gfortran.bat in directory
  C:\Program Files\gfortran\bin      content is:
"C:\Program Files\gfortran\bin\gfortran4.4.0" %1 %2 %3 %4 %5 %6 %7 %8 %9

That seems to do the trick for now, and it means I don't have the modify 
my make files.

An obvious limitations is that this allows only for 9 command line 
parameters.

Nevertheless, I think I can live with this for a while until a patch is 
available, thank you very much.


I am very impressed with the bug tracking system, and the team that 
handles it. I've posted some Vista problems before, which have been 
dealt with very promptly, resulting in an almost immediate new release.

Nevertheless, may I make a few suggestions?

- please keep the installers for the previous stable versions available, 
so that it is possible to regress to a version that worked; on the Wiki 
pages, only the last version is available, and that usually is an 
experimental one. Maybe I missed something and older versions are still 
available somewhere, but then this is not obvious.

- Much to my regret and undoubtedly to many others as well, Vista is 
here to stay; I didn't even have the option to install XP on my new 
laptop, and XP distribution will cease more or less soon anyway.
So I would strongly suggest to perform the same severe testing for Vista 
as you undoubtedly do for XP.



I am trying to convince my international colleagues to switch from g77 
to gfortran. Many of them still use g77, even though it is no longer 
supported or even officially distributed (you wouldn't believe what some 
of them do to install g77!).
However, some large Fortran libraries which were built a decade or so 
ago for g77, are still very much in use, with very little chance of them 
ever being updated. I have tried to build one of these from source, with 
the provided make files, using gfortran, but gave up very quickly after 
being inundated with errors and warnings.

In my experience, one of the main differences is the definition of 
structures, and the structure syntax (e.g. the use of "%" instead of 
"."). Is there a way (compiler option or something) to compile old code 
with old structure definitions, using gfortran, and without replacing 
them in the source code?


Once again, thank you very much for the valuable service you provide, 
and keep up the good work!


Thank you in advance,

Daniel Heynderickx
