[Bug libgcj/26495] New: problems with gcj-dbtool

["Thomas dot Arend at web dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

here is the result of a bootstrap under a recent cygwin using

  ../gcc-4.1.0-20060219/configure --prefix=/home/arend/opt/install/gcc-4.1.0
    --enable-languages=ada,c,c++,fortran,java,objc,obj-c++ --enable-libgcj
    --with-x --enable-java-awt=xlib --enable-threads
    --enable-version-specific-runtime-libs --disable-win32-registry
    --enable-libada --enable-libssp
--with-gmp=/home/arend/opt/install/gmp-4.1.4
    --with-mpfr=/home/arend/opt/install/mpfr-2.2.0-20060220
    --enable-target-optspace

Creation of the compilers was successful, but the java library tools made some
problems (snapshot from the 'make bootstrap' output):

...

./gcj-dbtool -n classmap.db || touch classmap.db
error: could not create classmap.db: java.io.IOException: mmap not implemented

uname -a produced "CYGWIN_NT-5.1 hhn0001 1.5.19(0.150/4/2) 2006-01-20 13:28
i686 Cygwin", the binutils version seems to be 2.16.91 20050610.

My impression is that cygwin does not fully support mmap. But following the
cygwin changelogs there seems to be a lot of activity in this area.

Regards,

        Thomas
