The test fails, because echo/cmd.exe does not like &, it expects a command 
after it:

Configuring the source directory...
int main(void) { return (unsigned long)
'foo' is not recognized as an internal or external command,
operable program or batch file.
d:/djgpp/lib/crt0.o(.data+0xc2):crt0.s: undefined reference to `_main'
d:/djgpp/lib/libc.a(crt1.o)(.text+0x404):crt1.c: undefined reference to `_main'
collect2: ld returned 1 exit status
junk: No such file or directory (ENOENT)
'junk' is not recognized as an internal or external command,
operable program or batch file.

After reading some manuals, this makes it work (don't know if this is 
applicable to other DOS variants):

echo int main(void) { return (unsigned long)^&foo %% 8; }           >>junk.c

(i.e. a ^ before &).

But defining DECL_ALIGN in config.h does not disable USE_LSB_TAG.  The only 
way, sort of modifying lisp.h of course, is to define USE_LISP_UNION_TYPE instead.
