From f65ca70deaf38db4ca12458e74cefd8ad9063956 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Netto Date: Mon, 6 Mar 2023 15:53:55 -0300 Subject: libio: Do not autogenerate stdio_lim.h Instead define the required fields in system dependend files. The only system dependent definition is FILENAME_MAX, which should match POSIX PATH_MAX, and it is obtained from either kernel UAPI or mach headers. Currently set pre-defined value from current kernels. It avoids a circular dependendy when including stdio.h in gen-as-const-headers files.
