I made minor changes to opt/praxis* to make f2c happy
(and updated /n/inet/netlib/opt accordingly).

Change to dqed.f (proposed by David Klein and confirmed
by Richard Hanson, to fix a bug with an infeasible start):
1916c1916
<           DO 70 I = 1,MCON + MEQUA
---
>           DO 70 I = 1,MCON + 1

Try to get the dqed.f change right:
1916c1916
<           DO 70 I = 1,MCON + 1
---
>           DO 70 I = MCON + 1, MCON + MEQUA

Minor updates from Richard Hanson to dqed.f (explained in comments).

Peter Spellucci's donlp2 supercedes his donlp; both are SQP codes for
general nonlinear programming with dense (non-sparse) linear algebra.

Minor changes to nnes: calling sequence in HLPCHK corrected; DATA
statements moved after declarations; useles rod.f removed.

More changes to nnes, replacing MACHAR by calls on the current
[ID]1MACH (to avoid trouble with some optimizing compilers).

Minor changes to nnes, source file deufls.f: adjust logic for the
case LAMBDA.EQ.ZERO so a return with ABORT=.TRUE. occurs independently
of whether OUTPUT.GT.0.
