make[5]: *** [java/lang/natDouble.lo] Error 1
make[5]: *** Waiting for unfinished jobs....

It turns out that this happens for the following reason: the invokation of
AX_CREATE_STDINT_H in libjava/classpath/configure.ac (from
libjava/classpath/m4/ax_create_stdint_h.m4, unmodified from upstream
http://cvs.sourceforge.net/viewcvs.py/ac-archive/ac-archive-5/guidod/) is
run with CFLAGS etc. explicitly cleared.

Since the IRIX 6.5 stdint.h contains this code:

#ifndef __c99
#error This header file is to be used only for c99 mode compilations
#else

this test tails to detect int_least32_t in <stdint.h>.  Later, natDouble.cc
is compiled by g++ (which defines __c99 on IRIX), so the definitions from
stdint.h are visible and produce both the redefinition warnings and the
errors about conflicting typedefs.

------- Comment #1 from ro at techfak dot uni-bielefeld dot de  2006-06-28 15:32 -------
Fix:
If the configure test is run with -std=c99, it correctly detects that the
IRIX 6.5 <stdint.h> is usable.  Unfortunately, I've not yet found the
proper way to both change the AX_CREATE_STDINT_H definition (best
coordinated with upstream, should perhaps use the new Autoconf 2.60
AC_PROG_CC_C99 macro?) so the configure test yields correct results, and
(with the hack of hardcoding CFLAGS=-std=c99 in the test) how to properly
pass down -std=c99 on IRIX 6.5 everywhere it is needed.
