[PATCH 0/2] MR4401: include: Don't use dllexport attribute for PE modules.

[Jacek Caban (＠jacek)]

Recent change to make unixlibs use hidden visibility made DECLSPEC_EXPORT being used in more cases. This means that it's used for PE modules as well, which is meant to be ignored since we use .spec files and winebuild-generated .edata anyway. This has some side effects:

- LLD correctly ignores dllexport when it detects .edata presence, but it also issues a warning:
`lld-link: warning: literal .edata sections override exports`

- AFAIR (I didn't verify), GNU LD would still generate its own .edata entries, but the one provided by winebuild will be actually used by PE header

- non-mingw builds will use default visibility for those symbols in PE modules
