 |Regardless, the current implementation is incorrect, as this declaration doesn't exist:
 |      extern "C" const char* strchr(const char*, int); 
 |     should be
 |      extern "C" char* strchr(const char*, int); 
  
 I am puzzled. Stroustrup says in his book "The C++ programming
 language" (special edition) on page 599:
 
 "Functions for manipulating C-style strings are found in <string.h>
 and <cstring>:
 ...
 const char* strchr(const char*, int);
 char* strchr(char*, int);"
 
 On the following page he mentions the "C standard library definition,
 not C++" of strchr:
 
 char* strchr(cont char*, int);
 
 This is the same as stated in the book "C, a refrence manual by
 Harbison and Steele. 
 
 Therefore, I believe, the prototypes in the current libstdc++
 implementation for strchr are indeed correct. 
 
 One has to cope with the different signatures for the C and the C++
 versions of the function strchr (among others). 
 
 Hope this is correct,
