Subject: [PATCH] configure: Remove several implicit function declarations
|
|
|
|
During configure, some checks omit the corresponding include. A compiler
|
|
defaulting to C99 mode could cause those checks to fail since C99 does
|
|
not allow implicit function declarations. This commit fixes the same.
|
|
The configure script is re-generated.
