--- Comment #7 from Costas Argyris <costas.argyris at gmail dot com> --- Created attachment 54575 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54575&action=edit Treat include path args the same way between cpp_unique_options and asm_options The proposed patch extends the logic already used for passing include paths down to the compiler (when a @file was given to gcc), also to the assembler. This unifies the logic and also avoids overflowing the Windows command line when many include paths have been passed to gcc through a @file.
