gcc 3.2 limits.h from crtstuff.c

[David Meggy <dmeggy at techsol dot ca>]

Hi, I'm trying to cross compile a native compiler.  I think there is
something wrong with the way it finds includes.  My neccessary
information and errors are below.  When the #include <limits.h> is made
from tsystem.h, gcc should first try ${my cross env}/include/limits.h
right?  Well it using the one from ./include/limits.h.  So now that this
one is calling #include_next <limits.h>, gcc can't find anymore
limits.h.  According to my inserted #warnings ${my cross
env}/include/limits.h is never called.

If someone could help, it would be greatly appreciated.

Dave



My build environment consists of gcc 3.2 configured as follows
./configure --target=arm-linux --host=i386-pc-linux-gnu \
--enable-target-optspace --prefix=${my cross env} \
--enable-languages=c --disable-multilib --disable-threads \
--with-gnu-ld --disable-nls --disable-shared

and the compiler I'm trying to build was configured like this
{gcc_source_path}/configure --target=arm-linux --host=arm-linux \
--build=i386-pc-linux-gnu --prefix=${my cross runtime env} \
--enable-languages=c --disable-multilib \
--disable-threads --disable-shared

I get the following error

I put in the #warning into the file {build_dir}/gcc/include/limits.h so
I could tell which limits.h it was using.
