Gcc version 4.3.2 gives the "differ in signedness" warning below when building
Biopython.

While my C is not very good, changing line 34 from 'unsigned char' to just
'char' removed the warnings. 


Bio/cstringfnsmodule.c: In function ‘cstringfns_splitany’:
Bio/cstringfnsmodule.c:34: warning: pointer targets in initialization differ in
signedness
Bio/cstringfnsmodule.c:71: warning: pointer targets in passing argument 1 of
‘PyString_FromStringAndSize’ differ in signedness
Bio/cstringfnsmodule.c:85: warning: pointer targets in passing argument 1 of
‘strlen’ differ in signedness
Bio/cstringfnsmodule.c:87: warning: pointer targets in passing argument 1 of
