Πόσο καλά τα πάει ο gcc με τα templates;

Mprabo. To opoio wstoso den erxetai se antifash me to :


       Options Controlling the Kind of Output

       Compilation can involve up to four stages: preprocessing, 
compilation proper,
       assembly and linking, always in that order.  GCC is capable of 
preprocessing and
       compiling several files either into several assembler input 
files, or into one
       assembler input file; then each assembler input file produces an 
object file,
       and linking combines all the object files (those newly compiled, 
and those spec-
       ified as input) into an executable file.

       For any given input file, the file name suffix determines what 
kind of compila-
       tion is done:

       file.c
           C source code which must be preprocessed.

       file.cc
       file.cp
       file.cxx
       file.cpp
       file.CPP
       file.c++
       file.C
           C++ source code which must be preprocessed.  Note that in 
.cxx, the last two
           letters must both be literally x.  Likewise, .C refers to a 
literal capital
           C.

Bebaia, to 8ema den einai sto compilation, alla sto linking. Wstoso 
8ymamai ston gcc 3.x na kanw compile C++ kwdika  (otan htan pragmatikos 
C++ kwdikas, dhladh ahdia epipedou 1 kai oxi ahdia epipedou 2 me

stous narkomaneis tou ISO commitee) xrhsimopoiwntas to gcc frontend. I 
consider this as a BUG and I PERSONALLY DEMAND FROM RMS TO IMMEDIATELY 
FIX IT, OR ELSE.
