RE: libiberty can't find target header files

[Teri McManus <Teri_McManus at Trimble dot COM>]

We are using VxWorks for Hitachi SH2.

To find target header files we need to use -nostdinc and -I for include
directories as shown in the following compile line.


ccsh -BC:\Tornado/host/x86-win32/lib/gcc-lib/ -v -c -m2 -ansi -nostdinc -O
-fvolatile -fno-builtin -Wall -I/h -I. -I../include -I../diag
-IC:\Tornado\target\config\all -IC:\Tornado\target/h
-IC:\Tornado\target/src/config -IC:\Tornado\target/src/drv -DCPU=SH7040 -o
%1.o %1.c
