Change RWORK description in the header. The RWORK array needs to be at least of
dimension 2*NMAX to accomodate the calls to CHESVXX in CDRVHEX, ZHESVXX in
ZDRVHEX, CSYSVXX in CDRVSYX, and ZSYSVXX in ZDRVSYX. (The dimension of RWORK in
the caller subroutines --, e.g., ZCHKAA -- is way large enough.)
