Would it be possible to add a -D_WIN32 to the libjava/libltdl Makefile

dynamic libraries can be loaded into GCJ apps.
No. If there is dynamic linking to be done it should work through
dlopen and pals. Defining _WIN32 is not the way to accomplish this.
Hmmm... I've been having problems compiling cvs-m4 which HEAVILY uses
the libltdl library-loading functionality. I wonder if it could be
related to this:
module = LoadLibrary(wpath);
module = LoadLibrary (searchname);
It appears that current libtool does in fact use LoadLibrary and not
dlopen. This worked fine in the past (perhaps pre-1.5.0?) but appears
to not work as well anymore.
Should the module-loading functionality in libtoool for cygwin be
reworked to use dlopen instead?
