g++ uses -pedantic-errors when compiling g++.dg/abi/bitfield4.C. When newlib is
being used its limits.h file ends with #include_next <limits.h> to get GCC's own
limits.h information. This causes the error 'include_next is a GCC extension'
so the test fails to build.
This is probably a problem with the way include files are passed to the compiler
in the testsuite, but it may also be a CPP problem.
The command-line used to compile the test is:
