You'll want to check those results carefully for any conformance test 
(gcc.dg/c[91]*) failures indicating header problems.  In particular, the 
testsuite verifies that C1X definitions are present in <float.h>; if they 
aren't present on NetBSD you'll want to keep GCC's <float.h> or fix 
NetBSD's with fixincludes.

If you always wish to use NetBSD's <stdint.h>, then the default 
use_gcc_stdint=none in config.gcc will work but you'll need to add 
configuration information to the compiler to tell it about the <stdint.h> 
types for all the c99-stdint-*.c tests to pass (this is needed for the 
Fortran C bindings, in particular); see 
<> and PR 448.  This is 
best done as a separate patch.
