I am having trouble with building the gcc 4.5.1 with --enable-plugin on Cyg=
win.
The configure string is "--enable-plugin --enable-languages=3Dc,c++ --disab=
le-bootstrap".
The error is ,
=A0 checking for -rdynamic... objdump: conftest: not a dynamic object no
=A0 checking for library containing dlopen... none required
=A0 checking for -fPIC -shared... no
=A0 configure: error:
=A0 Building GCC with plugin support requires a host that supports
=A0 -fPIC, -shared, -ldl and -rdynamic.
=A0 make[1]: *** [configure-gcc] Error 1

When I jump the -fPIC checking, it's success. And then failed when building=
 a gcc plugin, print following,

=A0 plugin.c:1:0: warning: -fPIC ignored for target (all code is position i=
ndependent)
=A0 /tmp/ccU93aXF.o:plugin.c:(.text+0xd1): undefined reference to `_build3_=
stat'
=A0 /tmp/ccU93aXF.o:plugin.c:(.text+0xff): undefined reference to `_gimple_=
assign_single_p'
=A0 .....

Thanks.
