Ah. Well, I see that this is the second time I broke stuff on stdint.h.

I must fix this correctly, apparently. 

Mine...

happens on sparc-solaris2.8 as well. sparc-solaris2.10 is not affected.

Sorry about the delay folks. Trying to track down some config issues, and so
far failing to get a local xcompiler up so I can test locally a config w/o
stdint.h provided.

Goal is to use GCC_HEADER_STDINT(gstdint.h) to construct a stdint.h that works
when stdint.h is not found. When stdint.h is found, do nothing.

I have a patch in testing. Looks ok so far.
One question, is it ok to place gstdint.h into the include directory? And not
like others in the toplevel build dir?

------- Comment #7 from bkoz at gcc dot gnu dot org  2008-04-16 18:39 -------

Hey Andreas. This is fine for the time being. 

If (include/gstdint.h) ends up being a problem (as include directory may not
exist when being output?), you can just do (gstdint.h) and then add a special
rule in include/Makefile.am for host_headers_noist to copy from  builddir to
include dir.

------- Comment #8 from bkoz at gcc dot gnu dot org  2008-04-16 18:52 -------

in configure.ac please put 

GCC_STDINT

out of native/cross bit of configure, and run unconditionally like so:

GCC_LINUX_FUTEX([AC_DEFINE(HAVE_LINUX_FUTEX, 1, [Define if futex syscall is
available.])])

GCC_HEADER_STDINT(include/gstdint.h)

------- Comment #11 from andreast at gcc dot gnu dot org  2008-04-20 21:00 -------
Compilation issues fixed. Both, on sparc and hpux. Confirmed myself.
We need to investigate the results of the atomic tests under HPUX. But if not
satisfying, we will open a new PR.
