"extern "C" void (*)(int)" cannot be converted to type "void (*)(int)"

[LouisCypher]

C language doesn't support namespaces, so extern "C" and namespaces are incompatible. Function defined inside of a namespace cannot be declared as extern "C".

Hello,

thank you for the reply - this code compiles successfully on cygwin unix emulator. Looks like it's up to compiler (IBM XL C/C++ in my case). What can be done in code to resolve this ?
