[apluslist] A+ compilation errors

[Vladimir N. Kutinsky]

Hello all,

Ive just tried to compile A+(4.20-1) and ran into a problem i cant seem to
solve on my own. This is what i did. I 'export'ed two variables CFLAGS and
CXXFLAGS setting them to -O3 and ran
./configure --prefix=/usr/local/aplus-fsf-4.20
This step seems to have worked okay. Then i ran 'make install' and this is
when the fun started. At first, i got the following messages(a snippet of
the result):
.........
In file included from pA_Connection.C:33:
/usr/include/g++/backward/iostream.h:35: error: `ostream' is already
declared
   in this scope

   introduced ambiguous type `ostream'
/usr/include/g++/backward/iostream.h:36: error: `istream' is already
declared
   in this scope
/usr/include/g++/backward/iostream.h:36: error: using declaration `istream'

make: *** [install-recursive] Error 1

I commented the 33th line of "pA_Connection.C" and ran make install again.
This time the script worked a lot farther and even managed to create a
/usr/local/aplus-fsf-4.20/lib directory with a dozen of libraries there, but
again ended up with an error:
..............

../MSTypes/MSSymbol.H:27: error:   first type here

make[1]: *** [install-recursive] Error 1

make: *** [install-recursive] Error 1

What did i do wrong? Can anyone help me please?

This is my environment:
SuSE Linux 9.2
gcc version 3.3.4 (pre 3.3.5 20040809)

Thanks in advance,
Vladimir
