I have released a new version of Seed7: seed7_05_20100404.tgz

In the Seed7 programming language new statements and operators
can be declared easily. Types are first class objects and therefore
templates/generics need no special syntax. Object orientation is
used when it brings advantages and not in places when other
solutions are more obvious.

Seed7 is covered by the GPL (and LGPL for the Seed7 runtime library).

- Many thanks to "Mensanator" for his help to investigate 64-bit and
    Mac OS X problems.
- The chk_all.sd7 check program was improved to check that the
    interpreted compiler and the compiled compiler generate the same
    C programs.
- Checks for 'set of char' were added to the "chkset.sd7" program.
- The compiler (comp.sd7) and the interpreter (hi) were improved to
    support the actions BST_EQ, BST_NE and BST_PARSE.
- The compiler (comp.sd7) was improved to support the actions
- The compiler (comp.sd7) was improved to make sure that the same
    types are used in generated C programs and in the runtime library.
- The generation of string constants in the compiler was improved to
    work correctly when the string size is stored as 64-bit unsigned
- The generation of set constants in the compiler was improved to
    work correctly when bitsettype elements have a size of 64-bit.
- The compiler was improved to use the union type 'valueunion'
    instead of 'float2int'.
- The functions arrBaselit, arrBaselit2, arrExtend and arrGen in
    "arr_rtl.c" were changed to use parameters of type rtlGenerictype
    instead of rtlObjecttype.
- The functions bigCmpGeneric, chrCmpGeneric, fltCmpGeneric,
    intCmpGeneric, refCmpGeneric, setCmpGeneric, strCmpGeneric and
    typCmpGeneric were introduced as compare functions with parameters
    of type rtlGenerictype.
- The functions bst_append, bst_cpy, bstAppend and bstCpy (defined
    in "bstlib.c" and "bst_rtl.c") were improved to work correctly when
    source and destination are identical.
- The function cmdConfigValue in "cmd_rtl.c" was improved to support
- Several makefiles were changed to define FLOAT_SIZE, DOUBLE_SIZE
- The functions bigCreateGeneric, intCreateGeneric, drwCreateGeneric,
    setCreateGeneric and strCreateGeneric were introduced as create
    functions with a parameter and a result of type rtlGenerictype.
- The function intDestrGeneric was introduced as destroy function
    with a parameter of type rtlGenerictype.
