compiling gnokii under Win32/VisulC++6.0...

[Cardascia Lorenzo]

Hi all,
I just downloaded the 0.4.3 distribution in order to compile it under
VisualC++6.0 and had some problems during compiling...

1. I had some not defined routine errors for serial_nreceived() and
serial_flush() while it was compiling device.c file.
For these errors I followed Mark Lakata's suggestion (found in a
previous email of 18 Sept)
related to copy the serial_nreceived() and serial_flush() subroutines from
unixserial.c into winserial.c, and remove everything except the last
lines that return the no error flag.
Has anyone written the serial_nreceived() and serial_flush() routines
specifically for win32?
(...but this errors don't worry me because I can go on using Mark Lakata's
patch).

2. I had another not defined routine error for alloca() routine called
in m2bus.c file. The snippet code follows:

*****************
static GSM_Error M2BUS_SendMessage(u16 messagesize, u8 messagetype,
unsigned char *message)
{
....
        if ((out_buffer = alloca(messagesize + 8)) == NULL) {
                dprintf("M2BUS: transmit buffer allocation failed, requested %d 
bytes.\n",
messagesize + 8);
                return GE_MEMORYFULL;
        }
....
}
*****************

Where is defined alloca() routine?
How can I do to solve that compiling error?
Perhaps I made a mistake, but Im not able to compile gnokii project if I
don't solve the rpoblem...

Let me know any suggestions, please.
Thanks a lot,
Lorenzo
