problem desciption: The preprocessor powerpc-eabi-pp seems to look for
header files in $prefix/$target/include while the files are in
$exec-prefix/$target/include
Hi,
I'm building gcc including newlib for powerpc-eabi under cygwin. The build
succeeds, however cpp does not find the newlib header files (e.g. stdlib.h)
when
building an application. It seems the default search path differs from the
real location of these files, see the output of 'powerpc-eabi-cpp -v' :
$ powerpc-eabi-cpp -v
Using built-in specs.
