/* Do not expand builtin functions (unless explicitly prefixed with
"__builtin"). Symbian OS code relies on properties of the standard
library that go beyond those guaranteed by the ANSI/ISO standard.
For example, "memcpy" works even with overlapping memory, like
"memmove". We cannot simply set flag_no_builtin in arm.c because
(a) flag_no_builtin is not declared in language-independent code,
and (b) that would prevent users from explicitly overriding the
default with -fbuiltin, which may sometimes be useful.
Make all symbols hidden by default. Symbian OS expects that all
exported symbols will be explicitly marked with
"__declspec(dllexport)". */
