            Bug ID: 65038
           Summary: Unable to find ftw.h for libgcov-util.c
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: libgcc
          Assignee: unassigned at gcc dot gnu.org
          Reporter: terry.guo at arm dot com

I am doing a clean trunk build for mingw and facing below issue:

/home/build/work/GCC-5-0-build/src/gcc/gcc/../libgcc/libgcov-util.c:55:17:
fatal error: ftw.h: No such file or directory
compilation terminated.
make[1]: *** [libgcov-util.o] Error 1

This looks very similar to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61889.

I had to revert patch as on boostrap libgcc now tries to test ability to
compile, which is of course not possible.
Other miracle is that configure.ac and actual present configure seem to be
divergent ...

Now fixed without regression.
Problem was that header-checks were done before gcc-no-execution.
