undefined reference when building GCC-4.8.1 MinGW-W64

undefined reference when building GCC-4.8.1 MinGW-W64

[i.nixman]

Hello guys!

a long time ago I successfully built this version of the GCC-4.8.1, and 
I'm pretty sure I used the same options.

but now, on stage3 I get a linking error:

any ideas?

I think this problem may occur due to the use of this patch:

https://github.com/niXman/mingw-builds/blob/develop/patches/gcc/gcc-4.6-fix_mismatch_in_gnu_inline_attributes.patch

right?

This patch has never been in mainline GCC.  And it's 2022 so you should
not use gcc-4.8 or 4.6 anymore.

great, but without that patch I still get the error:

For the sake of simplicity, I suspect it is possible to make `libc_name_p()` a `static __inline` 
function, as I see it be referenced only ever once in 'except.c'.

When attempting to compile 'except.c' as C++ with GCC 4.8 and with the patch which you have 
mentioned, this function is a `gnu_inline` function with an implicit `extern` [1], so rule 1.3 [2] 
applies: Because optimization is not enabled, a call to an external function is emitted; and because 
no out-of-line definition is available, undefined reference is the result.

Use of the `gnu_inline` attribute on an `extern` function requires there be a definition that is 
compiled without `gnu_inline` or `inline`. Probably it can be removed when `__cplusplus` is defined.


[1] This differs from C, where `inline` has a distinct meaning from `extern inline`.
