INT4 on Linux/2.2.9 (x86)

Hi,

I just installed PostgreSQL 6.5.3 on Linux 2.2.9 (Intel/x86) platform.
Everything went smoothly, but the regression tests failed for int2 and
int4 datatypes.  Repeated tests produced the same results.  Should I be
concerned that the SERIAL macros default to int4 for all their values?
Are int4 types corrupted or otherwise unavailable on this platform?

Sorry if this is in a FAQ somewhere... If so, I'd greatly appreciate a
pointer to the right direction. *smile*


    Thanks,
