While compiling libg++-2.3 with gcc-2.3.3 (both configured with
mips-sgi-irix4) on Indigo with IRIX 4.0.1 I got the following warning:

>gcc -g -O -nostdinc++ -I. -I.. -I. -I./../src -I./../g++-include -c  filebuf.C
>filebuf.C: In method `int  filebuf::do_write (const char *, int)':
>filebuf.C:284: warning: negative value assigned to unsigned quantity

The piece of code that the warning refers to is the following:

>int filebuf::do_write(const char *data, int to_do)
>{
>    if (to_do == 0)
>	return 0;
>    if (xflags() & _S_IS_APPENDING) {

_fb._offset is defined to be of type fpos_t in `strambuf.h' which is
unsigned in IRIX. This might not be anything serious but I thought it
was worth reporting.
