Avoid an undeclared exit function call in obscure configure check.
|
||
|
|
This improves compatibility with strict(er) C99 compilers, which may
|
||
|
|
not support implicit function declarations because they were removed
|
||
|
|
from the C language in 1999.
|
||
|
|
|
||
|
|
Not submitted upstream as regeneration of configure with new autoconf
|
||
|
|
would fix.
