Release history:

2.4o -- 8 May 2011

src/jal/build.sh was missing from the source package
generalized the PIC optimizer, converted the various optimizers (data, branch, movlp, movbsr) to use the new code.
don't allow variables named built-in functions (COUNT/WHEREIS/DEFINED)
FOR cexpr... where cexpr is one larger than a variable could otherwise hold (eg, 256 for a BYTE variable) will now work correctly.
FOR var... now works correctly. Formerly, if var was modified withing the loop the results could change.
Fixed documentation of FOR and the example for tasks.
There are times when a parameter to an inline function *cannot* be replaced (eg, if a constant is passed to a parameter, and the parameter is the master of another variable). bugreport_20100920
Moved the `# errors, # warnings' output to the very end, averting the confusion over how a file with errors or warnings will report `0, 0'
Added another error -- universal arrays require a constant subscript
A function returning a multi-bit caused the compiler to crash
Introduced records: RECORD id IS type id0 [ '[' cexpr ']' ][, ...] ... END RECORD
assign from str[0] fails when str is an array reference
add/subtract on 16 bit cores, where the destination is multi-byte and volatile does *not* need to be done in a temporary as is needed with the 12/14 bit cores.
casting with bits doesn't work correctly
bit indexing of arrays doesn't work correctly
fixed report where flexible arrays fail in 2.4o (bad fix to assign from str[0])
put the compiler version into the log file
The following: DWORD(t & !0xf) caused a compiler failure
Expanded the optimization sections of the JALv2 Compiler Options and JALv2 PRAGMAs documents.
Blindly checking for equality with (-1U) can lead to issues on machines with varying integer sizes (for example, a 64-bit machine with 32-bit unsigned, but 64-bit size_t)
Minor record issues: COUNT(xx.yy) and USING xx.yy did not work (xx was never fully dereferenced).
Fixed flexible arrays (accidently removed a counter bump)

2.4n -- 2 June 2010

added inline assembly statement mulwf (thanks hawkdavid52)
pic_value_is_zero doesn't work with pointers (bugreport_20100502)
broken arrays passed to functions (bugreport_20100523)
fixed `asm bank ' for 16 bit cores
Implicitly created pseudo-variables must be created in the same block as the true variable (bugreport_20100506).
On the 16 bit cores, if a pseudo-variable is implicitly created, the l_main label is somehow deleted causing the generated code to not work.
minor optimization when using 'case' with bit values. assign the bit to a temporary first to avoid shifting/masking for each case.
'case 0' on a multi-bit variable fails
Added 14 bit hybrid support (thanks Rob!)
Fixed the defined() operator to return a bit (as documented) so no more warnings or need to compare with 'true'
Issue a diagnostic if a value overflows a UNIVERSAL (is > 32 bits) (bugreport_20100424)
Allow octal constants (0q...)
In some circumstances an aliased value would get confused
Invalid assert on add with the 14 bit hybrid
The logic in UNIVERSAL value overflow was wrong, causing a spurious message in edge cases.
The MOVLB optimizer was not seeing functions only called indirectly.
Added '\\' to the language documentation.
