Re: Kawa 1.13 compilation problem, possible regression

Hi Per,

I tried to compile latest version (r7491) but was not able to do so
under java5. With java6, it went well and didn't hit any problems.
Here the failing bit when compiling with java5:

[kawac] (compiling c:\Nu\kawa\kawa\lib\rnrs\unicode.scm to
kawa.lib.rnrs.unicode)
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: unreachable procedure call
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: note - this
operand never finishes
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: unreachable procedure call
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: note - this
operand never finishes
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: unreachable procedure call
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: note - this
operand never finishes
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: unreachable procedure call
[kawac] c:\Nu\kawa\kawa\lib\rnrs\unicode.scm:117:11: note - this
operand never finishes

I checked the code in `unicode.scm` but could find something wrong
from my point of view. On a side note, from my first impression, the
changes you made seem to have worked since I do not see OutOfMemory
exception when compiling Kawa source code via `./configure && make` in
my CentOS box which was always the case before (first time was
failing, after that it was ok). So from this first test, I think it
should work great on my codebase.

Regards,
Matt
