[Rd] 8 char labels in read.spss

I was wondering why it is possible to read long labels from the CVS
files but not from the SPSS files.
I did not have much time to search for the code but I found:
in foreign_0.8-10 source file var.h.in
> /* Definition of the max length of a short string value, generally
> eight characters. */
> #define MAX_SHORT_STRING ((SIZEOF_DOUBLE)>=8 ? ((SIZEOF_DOUBLE)+1)/2*2
> : 8)
> #define MIN_LONG_STRING (MAX_SHORT_STRING+1)
> /* FYI: It is a bad situation if sizeof(R_flt64) < MAX_SHORT_STRING:
> then short string missing values can be truncated in system files
> because there's only room for as many characters as can fit in a
> R_flt64. */
> #if MAX_SHORT_STRING > 8
> #error MAX_SHORT_STRING must be less than 8.
I am am right then there was a restriction in the year 2000 because the
files are from the year 2000.
Now there are some questions:
Did I found the right code?
is it possible that anybody could recompile this with long value names
or where is the best manual for a quick start in compiling packages.
I found a couple of weeks before a tread where anybody wrote a complete
way for building packages.
He described all problems of him and there were a lot of hints for the
first steps, but I am not able to find it again - I don't know the
search terms which I used before :-(
