tccgen/win32: let __declspec(dllimport) imply extern Also, retain storage qualifiers in type_decl, in particular also for function pointers. This allows to get rid of this very early hack in decl() type.t \|= (btype.t & VT_STATIC); /* Retain "static". / which was to fix the case of int main() { static int (foo)(); ... Also: - missing __declspec(dllimport) is an error now - except if the symbol is "_imp__symbol" - demonstrate export/import of data in the dll example (while 'extern' isn't strictly required with dllimport anymore) - new function 'patch_storage()' replaces 'weaken_symbol()' and 'apply_visibility()' - new function 'update_storage()' applies storage attributes to Elf symbols. - put_extern_sym/2 accepts new pseudo section SECTION_COMMON - add -Wl,-export-all-symbols as alias for -rdynamic - add -Wl,-subsystem=windows for mingw compatibility - redefinition of 'sym' error for initialized global data 2017-04-04 09:34:52 +03:00			`__declspec(dllexport) const char *hello_data = "(not set)";`
