I have run into two subsystem installs during the execution of their install script: The first was matplotlib, the second during install of mathics.
Both failed due to gcc not being able to find "limit.h"
This is the error sequence for mathics (the install of matplotlib ended the same death):

I compiled a dummy prog (t.c) with
#include "limits.h"
and got this:
