Please enter a FULL description of your problem:
------------------------------------------------
Compilation failed on these three files, complaining about MAXINT being
undeclared:
src/backend/optimizer/path/costsize.c
src/backend/utils/adt/date.c
src/backend/utils/adt/float.c

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
I edited the three files so that the section that defines MAXINT matched
the definition in src/backend/optimizer/geqo/geqo_eval.c. My patch is
attached.
