The most reasonable guess from this bit:

> heaptuple.c:195: error: duplicate case value
> heaptuple.c:195: error: previously used here

is that sizeof(Datum) == sizeof(int32), as expected in a 32-bit build,
but yet tupmacs.h saw SIZEOF_DATUM == 8 and so we're trying to compile
the 64-bit version of store_att_byval().  All those warnings look like
there's something wrong about the Datum-size configuration, too.

What that suggests is that you're wrong about having "no issue in
./configure".  Maybe you previously configured for a 64-bit build
and forgot to reconfigure for 32-bit?  Or, if you're trying to do
a 32-bit build on a machine that's natively 64-bit, you did not
give the right compiler flags to configure so that it made its
decisions based on testing 64-bit behavior.

Redo the configure and make sure it reports 32-bit-appropriate values
for sizeof(long) and related tests.  *Don't* insert flags like -m32
post-configure: that has to be in the CFLAGS that configure sees.
