This is not exactly a bug report. This is just an observation of a
peculiar situation that might require fixing (propably not).

The IRIX-system header limits.h unconditionally defines for example
DBL_MAX. So does gcc's float.h but it undef's old definitions before
defining. If a program includes float.h before limits.h (like for
example Integer.cc in libg++-2.3 does) one gets a lot of warnings.
This may not be serious but the constants in system limits.h (and
system float.h) are also a bit different from the ones in gcc's
float.h.
