'symbol': file name too long

The length of a file pathname exceeds _MAX_PATH (defined by STDLIB.h as 260 characters). Shorten the name of the file.

If you call CL.exe with a short filename, the compiler may need to generate a full pathname. For example, cl -c myfile.cpp may cause the compiler to generate:

D:\<very-long-directory-path>\myfile.cpp
