[Libsysio-commit] HEAD: libsysio configure.in

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio
In directory sc8-pr-cvs6.sourceforge.net:/tmp/cvs-serv12453

Modified Files:
	configure.in 
Log Message:


The configure test for readlink was broken. The readlink module was
improperly forcing the BSD variance. This is in compliance with the
proper POSIX options.

One note:

The GNU includes just don't define a prototype for readlink sans extensions.
The choices made here should be the correct ones. Your mileage may vary...
