--- Comment #2 from Heiko Eißfeldt <heiko at hexco dot de> ---
I can reproduce this with cpp 6.3.0 on Ubuntu 17.04 amd64. No environment
variable setting is necessary.

And if I simplify your test case "a" to

#include "b"
#if 0
#endif

cpp does not see the '#if 0':
=======
cpp -traditional-cpp -ffreestanding -P issues/a
f

issues/a:3:0: error: #endif without #if
 #endif

#if 0
=======

So, it could have something to do with misparsing at the end of "b".
Fascinating...
