Application build in Eclipse gives error

[Amarnath MB]

Hi,

When I use "gcc  -E -P -v -dD test.c" from MingW shell it gives (Last few
lines)
int main()
{
 while(1);
 return 0;
}
ignoring duplicate directory

But when I give "arm-rtems5-gcc  -E -P -v -dD test.c"
int main()
{
 while(1);
 return 0;
}
ignoring nonexistent directory
"c:\opt\rtems\5.00\compiler\5\bin\../lib/gcc/arm-rtems5/7.4.0/../../../../arm-rtems5/sys-include"

COLLECT_GCC_OPTIONS='-E' '-P' '-v' '-dD'

Why does the path shown like
c:\opt\rtems\5.00\compiler\5\bin\../lib/gcc/arm-rtems5/7.4.0/include?
Is there a way to change it back to
c:/opt/rtems/5.00/compiler/5/bin/../lib/gcc/arm-rtems5/7.4.0/include?

* Thank you & Regards,*
