Details:

Small issue. Bug submitted for head but present in all releases I worked with
since at least v2.0.2.

A missing definition for sys_prot_t is the culprit:
========
In file included from src/core/init.c:42:0:
./src/include/lwip/sys.h:507:1: error: unknown type name 'sys_prot_t'; did you
mean 'sys_mbox_t'?
 sys_prot_t sys_arch_protect(void);
 ^~~~~~~~~~
 sys_mbox_t
./src/include/lwip/sys.h:508:25: error: unknown type name 'sys_prot_t'; did
you mean 'sys_mbox_t'?
 void sys_arch_unprotect(sys_prot_t pval);
                         ^~~~~~~~~~
                         sys_mbox_t
========

This only occurs if in lwipopts.h both NO_SYS and SYS_LIGHTWEIGHT_PROT are
used. If either or both are zero the error does not occur.

Attached is a small patch to fix this issue
