Version 1.4.0.
Fix assorted issues with undefined variables as detected by nagfor and other
compiler warnings.
In particular:
   * Eliminate unused array keep%rwork(:) in REAL versions only
   * Fix complex->real for arguments of alpha, beta of gram_c() in COMPLEX
     versions only
   * Give keep%n, keep%m and keep%kWork initial values so they can be legally
     used in array length definitions on subroutine arguments.
   * res argument to ea19_solve() becomes intent(inout)
   * Initialize arrays upon entry/allocation: keep%norms_Bx(:), lambdaZ(1),
     gramBA(:,:,:)
   * Fix several intents on ea19_reorder()
   * Various minor changes to types real/complex single/double for correctness.
   * Use abs(dot(...)) not dot(...) for norm in complex code (NORMALIZE_Y)

Version 1.3.1.
Minor change in specification (corrected reference to RAL TR).

2010-05-05
Version 1.3.0.
The computation of eigenvalue decrements has been made more reliable
by taking into account _SYGV eigenvalue errors and enforcing the cleanup
of the search directions when the eigenvalue decrements are too small
(close to or below the round-off error).

Version 1.2.0.
All blocks of the A-Gram matrix are computed explicitly for better
accuracy and reliability.

2009-11-13
Version 1.1.0.
A more rigorous procedure for detecting nearly-dependent vectors.
Lehmann bounds instead of quadratic residual bounds for eigenvalue errors.
The deflation error is eliminated by the restart on convergence
(previously this was only done for control%err_est = 1).
Residual vectors are orthogonalized to converged eigenvectors for correct
residual-based stopping criteria.
