"24" < INT_MIN returns TRUE ???

Hi,

did anyone compile latest CVS with v1.31
utils/adt/numutils.c?

Marc activated some range checks in pg_atoi() and now I have
a very interesting behaviour on a Linux box running gcc 2.8.1
glibc-2.

Inside of pg_atoi(), the value is read into a long. Comparing
a small positive long like 24 against INT_MIN returns TRUE -
dunno how. Putting INT_MIN into another long variable and
comparing the two returns the expected FALSE - so what's
going on here? long, int32 and int have all 4 bytes here.

Someone any clue?

Jan
