Update of /cvsroot/python/python/dist/src/Include
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv25741/Include

Modified Files:
	pyport.h 
Log Message:
Add a workaround for a problem that UTF-8 strings can be corrupted
or broken by basic ctype functions in 4.4BSD descendants.  This
will be fixed in their future development branches but they'll keep
the POSIX-incompatibility for their backward-compatiblities in near
future.

+ On 4.4BSD-descendants, ctype functions serves the whole range of
+ wchar_t character set rather than single byte code points only.
+ This characteristic can break some operations of string object
+ including str.upper() and str.split() on UTF-8 locales.  This
+ workaround was provided by Tim Robbins of FreeBSD project.  He said
+ the incompatibility will be fixed in FreeBSD 6.
