Patches for ocrad 0.10

What the patches are for

ocrad_0_10_old_gcc_or_no_getopt.patch.gz
The above patch makes it possible to compile ocrad version 0.10 on a system with an older version of the gcc-compiler (e.g. 2.96) or a system that lacks gnu getopts. It also compiles with Sun's CC compiler.

Description of changes

• A file called defs.h is included after inclusion of system headers. It undefines some macros for isalpha etc. and also checks for non-gcc compilers and avoids __attrib__((noreturn))
• In some functions, there were static looking dynamically sized arrays which have been replaced by std::vector.
• The use of getopts is disabled by default, but can be enabled by defining HAVE_GETOPT_H in the file main.cc. The help doesn't reflect that the long options do not work.
