Hello, one of my packages (tvtime) failed to build during the mass rebuild. Not a big deal, I think there are several ways to fix it. The odd thing is that the build failed due to a rather unexpected change in C++ preprocessor (g++ -E or cpp). Let's assume I have a test.cpp file containing this: #define MYMACRO(a, b) ""a", "b"" MYMACRO(x,y) Now `cpp test.cpp' (or `g++ -E test.cpp') on rawhide produces: # 1 "test.cpp" # 1 "<built-in>" # 1 "<command-line>" # 1 "/usr/include/stdc-predef.h" 1 3 4 # 1 "<command-line>" 2 # 1 "test.cpp" ""a", "b"" However on F23 or with `cpp -std=gnu++98 test.cpp' (`g++ -std=gnu++98 -E test.cpp') I got: # 1 "test.cpp" # 1 "<built-in>" # 1 "<command-line>" # 1 "/usr/include/stdc-predef.h" 1 3 4 # 1 "<command-line>" 2 # 1 "test.cpp" ""x ", "y "" Is this something known/documented? Or should I file a bug? I found this behaviour rather strange (but so are the macros in tvtime...).
