    /home/simark/src/binutils-gdb/gdb/../include/libiberty.h:711:38: error: invalid conversion from â??void*â?? to â??char*â?? [-fpermissive]
     # define alloca(x) __builtin_alloca(x)
                                          ^
    /home/simark/src/binutils-gdb/gdb/arm-linux-nat.c:578:13: note: in expansion of macro â??allocaâ??
           buf = alloca (VFP_REGS_SIZE);
                 ^
