Subject: [PATCH] Restore build on x86_64-w64-mingw32
|
|
|
|
* gold/configure.ac: Add checks for link, mkdtemp.
|
|
* gold/configure: Regenerated.
|
|
* gold/config.in: Regenerated.
|
|
* gold/plugin.cc (Plugin_recorder::init): Fall back to mktemp
|
|
if mkdtemp is not available.
|
|
(link_or_copy_file): Fall back to copy if link() is not available.
