I think too.
wchar_t is not handled in cpp. WCHAR_MAX becomes -1.
I updated patch of local-eabi-wchar.diff.
# This header was included by #444580.
Best regards,

Unlike other architectures, on Arm EABI, wchar_t is "unsigned int".
thus the default glibc definitions are incorrect:
#define __WCHAR_MIN (-2147483647 - 1)
#define __WCHAR_MAX (2147483647)
This causes miscompilation of atleast libidn, and possibly other
packages that use gnulib tests that check the correctness of wchar_t.
The attached adds a eabi specific bits.h.
