[Coin-discuss] Problems compiling Coin utilities with gcc 2.95 and 2.96

[John J Forrest]

I don't really see presolve_dupmajor as a problem as it does not seem 
likely to be used by any library writer.  There already is a 
CoinCopyOfArray in CoinHelperFunctions.hpp so it would be virtuous to 
change the copyOfArray but not urgent.

                 Ted writes `` ... what am I missing?''. To which I'd add 
``me, too''.

                 Templating, perhaps? There's a passle of non-templated 
definitions of
swap down at the bottom of 1.1.2.1 that persist through 1.10. Looks like 
the
trouble started when I condensed them to a single template. Newer versions 
of
gcc can deal with it, but 2.9[56] cannot?

                 John's fix --- move to CoinHelperFunctions -- looks to me 
to be the
way to go. Arguably copyOfArray and presolve_dupmajor should make the same
trip.  (Is there something in CoinPackedMatrix that is the functional
equivalent of presolve_dupmajor? I didn't notice it, but perhaps didn't 
look 
hard enough at the time.)
