I'm trying to build gcc 7.1 under cygwin32.
Older versions like 6.3 worked, but for 7.1 I'm getting:
undefined reference to `___divmoddi4'
This happens when I call "make install", because make went fine.
Any ideas what I'm missing, I could not find anything relevant?
TIA

----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/libexec/gcc/i686-pc-cygwin/7.1.0
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-LLIBDIR' linker flag
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
