hello,
whar I've done
1) extracted fresh gcc-4.9.4 archive

one can note that lib64/gcj-6.2.0-17/libjavamath.so is linked to system gmp not
gcc "embeded" one.
configure was run with the following arguments
'''
configure --prefix=/local/gensoft2/exe/gcc/6.2.0 \
--enable-threads=posix \
--enable-__cxa_atexit \
--disable-multilib \
--disable-bootstrap \
--enable-java-home \

FYI same problem with gcc-6.2.0
did I missed something ?
best regards
