Hm it seems the build scripts override the C99 setting. Tinc's configure script
detects it:

This will set CC to mipsel-linux-uclibc-gcc -std=gnu99 in the Makefiles.
However, later on when make is called, CC and CFLAGS are being overridden:

So change the scripts you have for building tinc for OpenWRT, and make sure it
does not override CC, or find some way to add -std=gnu99 to it.
