+Subject: [PATCH] libguile: Check for strtol_l during configure
+
+strtol_l is a gnu extention which may not be available on other linux
+libc implementations e.g. musl. Therefore check for this funciton and
+conditionalize the use of it.

+DESCRIPTION = "Guile is the GNU Ubiquitous Intelligent Language for Extensions,\
+ the official extension language for the GNU operating system.\
+ Guile is a library designed to help programmers create flexible applications.\
+ Using Guile in an application allows the application's functionality to be\
+ extended by users or other programmers with plug-ins, modules, or scripts.\
+ Guile provides what might be described as 'practical software freedom,'\
+ making it possible for users to customize an application to meet their\
+ needs without digging into the application's internals."
