Issue #11 has been updated by Usaku NAKAMURA.

Priority changed from Normal to Low

Bug #11: prelude.c compilation problem on mswin32  
[http://redmine.ruby-lang.org/issues/show/11](http://redmine.ruby-lang.org/issues/show/11)

Author: Usaku NAKAMURA  
Status: Open  
Priority: Low  
Assigned to: Usaku NAKAMURA  
Category:  
Target version:

Congratulations of starting mail transfer system of redmine.r.o.!

BTW,  
on mswin32, after prelude.rb is updated and the contents is not changed  
(such as ``touch’'ed), prelude.c will be always compiled.  
This is a rare case, so priority is low.
