Another candidate for fixing:

g++  -I.     -g -O2 -MT strcasecmp.o -MD -MP -MF .deps/strcasecmp.Tpo -c -o 
strcasecmp.o strcasecmp.c
In file included from mbchar.h:149,
                 from mbuiter.h:101,
                 from strcasecmp.c:29:
/usr/include/string.h:326: error: declaration of `int rpl_strcasecmp(const 
char*, const char*) throw ()' throws different exceptions
strcase.h:34: error: than previous declaration `int rpl_strcasecmp(const char*, 
const char*)'
/usr/include/string.h:330: error: declaration of `int strncasecmp(const char*, 
const char*, size_t) throw ()' throws different exceptions
strcase.h:40: error: than previous declaration `int strncasecmp(const char*, 
const char*, size_t)'
make[2]: *** [strcasecmp.o] Error 1

It looks like the strcase module needs to check in m4/strcase.m4 whether 
<string.h> provides a definition for strcasecmp, and use that knowledge in 
lib/strcase.h rather than blindly providing a conflicting rpl_strcasecmp.  But 
I'm not sure of the best approach for a patch.
