Subject: [PATCH] m4/fp_leading_underscore.m4: Avoid implicit exit function
|
||
|
|
declaration
|
||
|
|
Content-type: text/plain
|
||
|
|
|
||
|
|
And switch to a new-style function definition.
|
||
|
|
|
||
|
|
Fixes build issues with compilers that do not accept implicit function
|
||
|
|
declarations.
