Pragma directive or predefined for source charset?

[Christopher Jones <cpj_public@xxxxxxx>]

Hi all,

I've discovered the -fexec-charset flag. However, after reading all  
the documentation and wading through the gcc source, I still haven't  
found a way to get the value of -fexec-charset at compile time via a  
predefined macro or some kind of pragma directive to control the  
encoding. IBM's XL C/C++ compiler has #pragma filetag to specify the  
charset used in creating the source file, as well as the __FILETAG__  
macro which expands to a string literal representing the character  
coded set of #pragma filetag. It's also got the #pragma convlit  
directive to force the compiler to change the assumed codepage for  
character and string literals within the compilation unit. Is there  
anything like these in GCC? For all my hardcoded string and character  
literals, I need to know the source codeset so I can convert them to  
the user's locale.
