I build emacs-unicode-2 in winxp with MinGW, and it failed in /lib-src.

It says that the compile could not find the definition of EXIT_* and
NO_RETURN in hexl.c and ebrowser.c and sorted-doc.c.

In hexl.c, I added
#include <stdlib.h>

Can you explain why this problem doesn't happen on HEAD?  AFAICS, the
MinGW build of Emacs pulls in stdlib.h from src/s/ms-w32.h, which is
included by config.h.  Can you see why this doesn't happen for you?

in ebrowser.c, I added
#define NO_RETURN

Shouldn't be needed, either: NO_RETURN is defined in config.h.

NO_RETURN is defined in config.h, like this:

474 #ifndef NO_RETURN
475 #if defined __GNUC__ && (__GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR >= 5))
476 #define NO_RETURN       __attribute__ ((__noreturn__))
477 #else
478 #define NO_RETURN       /* nothing */
479 #endif
480 #endif

maybe is skipped by line 475.

and in sorted-doc.c, I added
#include <stdlib.h>
in #ifndef HAVE_STDLIB_H

Same here.  It sounds like your compilation doesn't include config.h
for some reason, or maybe config.h is empty.  Please try to see why.

IMHO, config.h was included. But could you teld how to confirm it?

Probably for the same reason: the Windows build is not supposed to
compile the code that uses the `link' function.

I havn't known how to resolve this problem.
