MKDIR_P vs. mkdir_p and automake versions

[David Bruce]

Hello, 

If I understand correctly, "MKDIR_P" is recommended but requires automake-1.10 
or higher.  Is this right?  I recently had a new developer on our free 
project tell me he needed to replace "MKDIR_P" with "mkdir_p" in the 
autotools-generated makefiles to get the project to build, and I'm wondering 
if the problem was that he didn't have the current automake.

Also, if he can't/won't upgrade to 1.10, is there an acceptable workaround?

Thanks,
