This is a known problem, due to a bad interaction between dubious code
and certain versions of gcc, in the file src/libes/edit/edit_cellhd.c
(if you check the output from "make", you will find that the first
error references this file).

Doing any one of the following should solve the problem:

1. Update to a later version of GRASS (it's fixed in the final 5.0.0
release).

2. Update just that file from the CVS archive; the following URL will
provide the correct version of that file:

http://freegis.org/cgi-bin/viewcvs.cgi/*checkout*/grass/src/libes/edit/edit_cellhd.c?rev=1.4

3. Fix the file manually, by changing the return type of
format_value() from "double" to "void".

4. Try changing the optimisation switches, e.g.

	CFLAGS='-g -O3' ./configure ...
or
	CFLAGS='-g -march=pentiumpro' ./configure ...
