Subject: [PATCH 1/2] configure: Specify correct function signatures and
|
|
declarations
|
|
|
|
Include needed system headers in configure tests, this is needed because
|
|
newer compilers are getting stricter about the C99 specs and turning
|
|
-Wimplicit-function-declaration into hard error e.g. clang-15+
|
