header includes for gcc-4.3 compatibility
...
minimal changes required to build without error
tested with gcc-4.3 (Debian 4.3-20071130-1) 4.3.0 20071130 (experimental)

LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

Proper padding of constant bitwise operands
...
When evaluating bitwise binary expressions at compile time, get the
signed/unsigned padding correct. Pay special attention to the case
of $signed/$unsigned changing the signedness of the operand.

Fix code generation for real expressions
...
Real value are vector width of 1, fix real literal to reflect this.
fix leaking real registers in code generation for function arguments.
Load of signal should handle conversion from real to vector. Function
arguments, type vector passed a real value, are an example where this
comes up.
