`configure options...` says:
checking for data_start... yes
(There's nothing about data_start in config.log .)

#define HAVE_DATA_START 1

Nothing is returned. What `make' does then is:
gcc -std=gnu99 -c -Demacs -I. -I/Work/emacs/src -I../lib
-I/Work/emacs/src/../lib -I/usr/include/freetype2 -D_REENTRANT
-I/usr/include/librsvg-2.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
-I/usr/include/gdk-pixbuf-2.0 -I/usr/include/cairo -I/usr/include/libpng15
-I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libxml2
-I/usr/include/freetype2 -MMD -MF deps/vm-limit.d -MP
-I/usr/include/p11-kit-1 -g3 -O2 vm-limit.c
Letting `configure' label Cygwin as it doesn't have data_start
might be one solution.
Thanks.
