One of the awk scripts used during the Open64 build currently requires
a GNU extension. On Ubuntu 10.10, the default awk program is mawk
rather than gawk as on most other systems. With mawk the script fails
and prevents the Fortran FE from building.
To make things a little easier, I propose the following patch that
changes the script to use only traditional awk features. The output
of the script is identical.
With the patch applied, I am able to build from source on Ubuntu 10.10
without the added step of changing the default awk program.
Suneel, let me know if you think this change should go into the
release. Thanks,
