Solaris 8 -> Sol 7 cross-compiler problem

[miki dot shapiro at eAladdin dot com]

Hi!

After an (apparently) successul compilation and installation of cross
gcc-2.95.2 for host sun-sparc-solaris2.8 and target sun-sparc-solaris2.7,
I'm trying to compile one of our projects. After having compiled all but
the last of the cpp files *successfully*, the last one explodes with a
million #pragma "warnings" (that result in a compilation halt):

=== end-snip ===
there is a lot more of these.
Now, added to this, I don't understand one thing:
1. If I:
     a. rename /usr/include to something
     b. rename /usr/local/include to something
     c. write a hello world proggie that does an #include <stdio.h> and
compile it (using the native solaris 8 gcc)
It works! it takes the header, namely stdio.h,  from someplace. FROM
WHERE?!

2. If I remove the "-I/usr/local/sparc-sun-solaris2.7/sys-include" from my
projects makefile, It compiles just fine. It probbably takes the headers
from the same place as the above hello world program. I am *VERY CONCERNED*
these headers are Solaris-8 specific and not Solaris-7 specific.
Furthermore, shouldn't I be using the headers I copied from a sol7 box and
notified the cross-gcc of when I compiled it using the --with-headers=
option to its configure? Common sense says I should.. :-)

Any help would be appreciated..
