configure: Add fake prototypes for C99 compatibility
|
|
|
|
The xxmc-related configure probes assume that the compiler
|
|
supports implicit function declarations because it tries to
|
|
call the functions without including the appropriate headers,
|
|
for link testing.
|
|
|
|
As the headers are not determined yet at this point, use
|
|
a fake prototype (the same that autoconf uses) to avoid
|
|
the implicit function declarations.
|
|
|
|
This avoids altering the outcome of these checks with future
|
|
compilers which do not support implicit function declarations.
|
|
