I see. (Thinking about it, the fact that MinGW doesn't have sys/wait.h 
should probably have been sufficient to tell me that sys/wait.h should not 
be present :-)

I guess that's possible - though I can find no evidence of it except for 
when it comes to building MinGW.

I've now switched to an independent and clean build directory - but the 
problem still persists.

It turns out that 'auto-build.h' is defining HAVE_SYS_WAIT_H. And I guess 
that's based on what configure produces. Perhaps I'm supplying a bad 
argument to configure ?  Here's what gcc-3.4.5-build.sh now looks like:

--------------------------------------------
#!/bin/sh
../gcc/configure --with-gcc --with-gnu-ld --with-gnu-as --host=i386-pc-mingw32 
 --target=mingw32  --prefix=/home/rob/mingw_vista --enable-threads=win32 --disable-nls 
 --enable-languages=c,f77 --disable-win32-registry --disable-shared --enable-sjlj-exceptions 
 --without-x --enable-interpreter --enable-hash-synchronization  --disable-bootstrap 
 --build=i686-pc-linux-gnu
make CFLAGS="-O2 -fomit-frame-pointer -D__USE_MINGW_ACCESS" 
CXXFLAGS="-mthreads -fno-omit-frame-pointer -O2" LDFLAGS=-s 2>err.log
#make -C gcc CFLAGS="-O2 -D__USE_MINGW_ACCESS" LDFLAGS=-s gnatlib_and_tools
--------------------------------------------

If those configure args are ok then I can only think that there must be some 
"cross pollution" as mentioned above.

Below my sig is the entire output of running 'sh gcc-3.4.5-build.sh'.
Configure twice tries to find sys/wait.h. The first attempt fails, but the 
second succeeds - and it's that success which (I'm assuming) leads to the 
defining of HAVE_SYS_WAIT_H in auto-build.h.

Just to repeat the error I'm getting (which gets written to err.log):

---------------------------------------------
In file included from ../gcc/genmodes.c:23:
../gcc/system.h:252:22: sys/wait.h: No such file or directory
make: *** [genmodes.o] Error 1
