When you get mysterious token errors appearing in source code, the
culprit is almost always a rogue macro defined by the compiler or by
some header earlier in the build process.

Look at the untainted source line, see what originally is there and look
for what could make it expand in a way you don't expect it to.

Single-letter macros tend to be more common than you think, it could be
as simple as a
#define M __T13
sneaking in from the toolchain you use.
