Try to configure with `--disable-shared --enable-shared=lto-plugin'.

Yes, it seems that linker plugin handling on cygwin is not done well.
Is linker plugin built for you and does the linker support it?

lto and linker plugin was OK in 20110101 snapshot
in which '-fuse-linker-plugin' was off by default
but in rev 168594, the option becomes on by default
this option causes checking LTOPLUGINSONAME in gcc/gcc.c (line
6812 around), which is not built with '--disable-shared'
something is wrong either with makefile or with gcc/gcc.c

Yes, I've changed the default when linker is detected to have linker support and
lto-plugin is build.

How this worked before?
On windows I would expect LTOPLUGINSONAME to point to the plugin DLL...

Hi,
is this dup of PR47225? I.e. is the --disable-shared the problem?
