Follow-up Comment #2, bug #61106 (project lwip):

I only came up with this other ugly patch to change strcat into
a strcpy for this one place and only for gcc.
(I'll upload this as lwip-gcc.patch here.)

I've only tested gcc-9 and gcc-10 to throw a warning, no test with
gcc-11 or other versions on this.

Not sure if you want to include this change into official sources,
I will just add this to local changes to keep going.

best regards,

Florian La Roche
