[Wien] Regarding lapw1

[Sharat Chandra]

Dear Wien2k users

I tried to install the newest vesion of WIEN2k on a single CPU RedHat 9.0
linux system running Lahey 95 compiler. There is a small bug in the hns.F 
in lapw1 directory, which does not allow the program to be compiled for 
the sequential case. There is a declaration in hns.F on line 82

      INTEGER, EXTERNAL :: NUMROC 

This is used only in the parallel executions, but is not commented out for
the sequential version of the extracted program and so the compiler is not
able to compile the program properly. This variable is available only in
the scalapack library and so we can not compile using just the blas and
lapack libraries. Just commenting out this line compiles the lapw1 without
any problems.

Hope this is of help.

Regards
