Fixed bugs:

• Control characters in symbol were printed non hex scalar value. #55
• #!fold-case only folded one expression. #56
• Overwriting or redefining didn't raisen an error. #57
• Invalid rename clause in export caused SEGV. #58
• c-struct-set! didn't accept struct pointer. #60
• Toplevel (values) caused exit. #62
• syntax literals was not compared in sense of free-identifier=?. #61
• Fixed bunch of unbound variables.
• cond-expand in define-library was not R7RS compliant.
• (rfc ssh) was not using identification string properly.
• copy-binary-port didn't copy all port content when src port contains more than 4092 bytes.

Improvements:

• ldconfig will be called after make install. #59
• exporting unbound variable now either reports warning or raises an error.
• Slightly better performance of port locking.
• Compiler now folds exported variable when the VM mode does not allow to overwrite.
• RSA and DSA marker is now defined with keyword so that compiler can constant fold.
• define-method won't add method to global definition when it's running on child context.
• (odbc) can now handle full DSN.
• Bignum and flonum in compiled cache now uses smaller amount of space.
• Compilation time error now has more information.

New features:

• define-c-union has been added to (sagittarius ffi) to support C union.
• c-memcpy has been added to (sagittarius ffi) for better performance.
• (tlv) now also supports LV structure reading.
• format now prints bytevector in hex, octec and binary numbers with ~x, ~o and ~b respectively.

Incompatible changes:

• Bytevectors are written with #u8() notation in R7RS mode.
