   As per your instructions I checked out the latest CVS sources. I had a
question here though. Since the 64-bit changes have been merged with the
main branch, both of the following will give me the up to date version,
right?

"cvs -d :ext:address@hidden:/cvs checkout -r branch-64-bit-merge
octave"

"cvs -d :ext:address@hidden:/cvs -z 9 checkout octave"

Or am I mistaken & should use only the second one?

    I am using autoconf 2.57, do you think that is the cause of the error?

    The reason I had to use "--with-f77=ifort" is because, if I used
only "F77=ifort", for some strange reason octave was configured to use
f77. Is this a bug?

    My mistake. A typo in the e-mail. The actual prefix mentioned was
"/home/aakash/octave". So that is fine.

Thanking you,
