I was under the impression that the root cause was a problem
with configure.ac in gcc rather than autoconf. However, I took
a look at that file, and I can only see a couple of references
to sys/types.h, none of which look the same as the sort of
thing I needed to change.
/* end confdefs.h. */
#include <stdarg.h>
#include <stdio.h>
+ #if !defined(__MVS__)
#include <sys/types.h>
#include <sys/stat.h>
+ #endif
cat >>conftest.$ac_ext <<_ACEOF
/* end confdefs.h. */
#include "confdefs.h"
+ #if !defined(__MVS__)
#include <sys/types.h>
+ #endif

I am running on a Linux box! The thing I am doing that is unusual
is two things:
1. Only providing C90 headers when cross-building a host. That
means that things like sys/types are failing.
2. No linking is done, because I don't have a cross-linker.
As far as I can tell, peculiarity number 2 has not caused the need
for any changes, with the possible exception of ones like this:
+ #if !defined(__MVS__)
#include <sys/types.h>
#include <sys/param.h>
+ #endif
+ #if defined(__MVS__)
+ #define BIG_ENDIAN 1
+ #define LITTLE_ENDIAN 2
+ #define BYTE_ORDER 1
+ #endif
I'm not sure what that one was all about, and I'm not sure the
result of it is even used.
Note that peculiarity 2 ideally requires prototypes for all
functions, so there were a couple of other changes made to the
gcc 3.4.6 code, such as this one:
#ifdef HAVE_SYS_RESOURCE_H
#include <sys/resource.h>
#endif
! #if defined (HAVE_DECL_GETRUSAGE) && !HAVE_DECL_GETRUSAGE
extern int getrusage (int, struct rusage *);
#endif
--- 86,100 ----
#include "prefix.h"
#include "gcc.h"
#include "flags.h"
#ifdef HAVE_SYS_RESOURCE_H
#include <sys/resource.h>
#endif
! #if defined (HAVE_GETRUSAGE) && !HAVE_DECL_GETRUSAGE
extern int getrusage (int, struct rusage *);
#endif
Anyway, all of this should be reproducible building any ASCII
target on any ASCII machine, just by using a C90 set of head
files and a dummy compile script like this:
C:\devel\gccnew\gcc\config\i370>type i370-mvspdp-gcc
echo $* >>/tmp/build.txt
i370-mvspdp-xxx -Werror-implicit-function-declaration -DPUREISO -S -I
/devel/mvshead/usr/include $*
Note the '-S' which could be '-c' instead and the -W.

Those are all available on the build machine, even though, out of those,
only m4 is available on the host. :-)
