This problem is caused by zero-byte of 
${builddir}/host-i686-pc-cygwin/specs
and the specs file is created by bootstrapped gcc executable.
the bootstrapped gcc crashes when generating specs file, which is the 
cause of the problem mentioned in this report. the maintainer of gcc 
should have experienced this problem.
to workaround this problem, the package maintainer needed to supress 
C{XX}FLAGS -static-libgcc -static-libstdc++ in 
host-i686-pc-cygwin/gcc/Makefile.
