The problem seems to be that HAVE_DATA_START is defined to 1, but
DATA_START is not defined. See below.

I think it's automatically prepended.

configure:10083: checking for data_start
configure:10099: gcc -std=gnu99 -o conftest.exe -g3 -O2 conftest.c >&5
configure:10099: $? = 0
configure:10107: result: yes

1

It's declared as
extern char data_start[];
but never defined. Apparently DATA_START is not defined. How is that
supposed to happen?
