thanks. is that a 4.02 option? i can not find them on my 3.4 gcc man page.

how it going on? have it been alreay available in 4.02?

that seem ok since i currently only need gcc. and, because i am new to the
field , i want to ask, what is a 'simulator'? run target excutable on host
computer?

sorry, are you the author of the new m16c/gcc code? i noticed your domain name
is redhat.

do you mean, the current m16c/gcc code never compiler c++ code? if so, that is
definitely a bad news to me, since our project based on EC++ (Embedded
C++). though you pointed that i could build for my self, but in fact i can not,
i know nothing about compiler writing :(

so, i am thinking another question. if i can write the code which can pass both
the current (3.4) g++ compiler and the IAR M16C C++ compiler, so my problem
will resolved. but is it possible of the idea? i think i can use some #ifdef
statements and move any IO into stubs. how different are these two compilers
in C++ syntax?

i like to heard any suggestion, and thank you in advance.
