These are supposed to be both functions and macros. I'm not sure
how to provide the functions at the same time as the macros,
as they collide with each other and cause compile errors.
However, some ports fully expect them to be functions.
For example, OpenSSH stores them into structures as function
pointers.
This reverts commit 4e79a60b78.
This broke the GCC port. Apparently isblank() was added in C99 and for
some reason it needs special treatment in headers.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
