7.3.2 Regression Failures Worth Looking Into

NetBSD 1.6 / Alpha (64-bit)
Postgresql 7.3.2 & 7.4-dev
gcc-3.2.2

I compiled 7.4-dev and had success with all regression tests. However when
I went back to 7.3.2, about 15 out of 89 tests failed.

I'll be using 7.4-dev, but I'm wondering if it's worth it to the
Postgresql community if I dig further to see why those tests failed;
considering that obviously 7.4-dev fixed all of them.
