Seed7 Release 2008-04-20

Hello,


I have released a new version of Seed7: seed7_05_20080420.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).


Changelog:
- An explatation how to uncompress the Seed7 package was added to
    the FAQ.
- The descriptions of the functions log2, gcd, lowestSetBit, 'rem',
    'mdiv' and 'mod' in the manual were added or improved.
- The functions gcd and modInverse were added to the bigint.s7i
    library.
- The bigrat.s7i library was changed to use the gcd function from the
    bigint.s7i library.
- The chkbig.sd7 program was improved with additional checks for the
    monadic plus, 'div', 'rem', 'mdiv', 'mod' and bigInteger constants.
- The chkexc.sd7 program was improved with additional checks for
    bigInteger functions.
- The chk_all.sd7 program was improved to take the new checks into
    account.
- The compiler (comp.sd7) was improved to work also with GMP's
    bigInteger's.
- The compiler was improved to support big_plus and big_gcd.
- The handling of +:=, -:=, *:=, <<:= and >>:= in the compiler was
    improved to avoid memory leaks.
- The handling of the bigInteger 'mdiv' and * in the compiler was
    improved to do some optimisations like using shift operations
    instead.
- Three example programs printpi1.sd7, printpi2.sd7 and printpi3.sd7
    were added.
- The big_gmp.c interface library was added to allow bigInteger
    computations based on the mpz_ functions of the GMP library.
- The file big_rtl.h was renamed to big_drv.h.
- The file biglib.c was change to allow working with big_rtl.c or
    big_gmp.c .
- The file big_rtl.c was improved to work with a BIGDIGIT_SIZE
    of 32.
- The functions bigHexCStri, uBigMultSub, uBigSqare, bigClit,
    bigCmpSignedDigit, bigDiv, bigGcd, bigGrow, bigImport, bigLShift,
    bigLShiftAssign, bigMDiv, bigMod, bigOdd, bigRem, bigRShift,
    bigShrink and bigToBStri of the file big_rtl.c were added or
    improved.
- An error message about "match value failed" was suppressed in
    dcllib.c .
- The int_mdiv action (defined in intlib.c) was improved for speed.
- The function prot_bigint (defined in traceutl.c) was changed to
    use bigHexCStri.
- The function printtype (defined in traceutl.c) was changed to
    avoid writing a pointer value.
- A bug in the function typHashCode (defined in typ_data.c) was
    fixed.
- The file read_me.txt was improved to contain a chapter about
    warnings and a chapter which explains how to use the GMP library.
