Subject: [PATCH] configure.ac: correct the getprotobynumber_r test
|
|
|
|
The AC_TRY_COMPILE test succeeds even when libc does not provide the
|
|
tested symbol. The compiler produces a warning, but exits successfully.
|
|
Use AC_TRY_LINK that will only succeeds if libc provides the symbol.
|
|
|
|
This fixes build with musl libc that does not support
|
|
getprotobynumber_r().
