[apluslist] FW: A+ compilation errors

[Daniel F. Fisher]

I poked around a little and googled some. The use of  "#include 
<iostream.h>" appears to be deprecated in favor of "#include 
<iostream>". Perhaps this will help clear things up. Alternatively, I 
see some mention of a compiler flag to all deprecated constructions. 
Here is one source: 
http://r-resc.a-eskwadraat.nl/archive/att-0968/01-makeoutput2 . I am 
also suspicious of places in the A+ source in which istream and ostream 
are declared directly rather than relying on a #include.

Hope this helps, but I only lurk out of nostalgia.

P.S. http://www.web-polygraph.org/mail-archive/users/200308/0000.html 
seems to show a similar pathology.
