Incorrect global variable compilation error in nginx

[TheDan64]

Running the noop traversal script over a freshly translated nginx gives you these weird compilation errors:

error: expected identifier, found keyword `mut`
 --> <anon>:1:12
  |
1 | pub static mut inc: uint64_t = 1i32 as uint64_t;
  |            ^^^ expected identifier, found keyword
help: you can escape reserved keywords to use them as identifiers
  |
1 | pub static r#mut inc: uint64_t = 1i32 as uint64_t;
  |            ^^^^^

However, when you run it a second time you don't see these errors anymore
