About specs syntax, see Chapter 3-15 of GCC Manual for more information. Generally, it uses builtin specs which is already compiled inside 'gcc' driver. But it also provide a chance that users can dynamically apply their own specs without rebuilding gcc program. In your case, gcc/g++ detected 'specs' appears under your working directory so it tried to read specs syntax from it but failed. Best regards, jasonwucj
