Does any g77 support >2Gb files?

Does any g77 support >2Gb files?

[Jay W. Parker]

We've got fortran applications on i686 machines that are growing 
files soon to surpass the 2 Gb limit, and other fortran applications 
running ~10 Gb files on VMS systems which we'd like to port to Linux.

I'm currently failing to produce large files with Redhat 7.1 g77 (gcc 
2.96). Do I need some other compiler? Linux release? g77 compilation 
flags? (I've tried g77 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE. . 
. without sucess, not a great surprise).

Please give me some idea how Fortran fits in with LFS, on any current 
or future system.

Support for >2Gb files on Linux (when using glibc 2.2 or higher) will be
in GCC/g77-3.1.  It is in the CVS trunk since the second week of July.

Hope this helps,
