Subject: Re: [Discuss-gnuradio] Build failure - caused by posix_memalign.cc-
in trunk built under Cygwin

Isn't <malloc.h> what was added in the first place to
posix_memalign.cc, which caused this issue?
No. What caused the issue is that valloc is not defined in the standard
place (<stdlib.h>) on Cygwin; <malloc.h> was added to fix the problem on
Cygwin, but it caused problems on other platforms.
I'm good with adding in malloc.h into configure.ac, then into
posix_memalign.cc with proper #ifdef around it. That will work with
OSX, and won't hurt Linux, and sounds like it'll allow Cygwin to work.
Eric / Johnathan ... comments? These are small / easy changes. - MLD
This sounds good to me as long as there is no hazard in including <malloc.h>
on other (non-Cygwin) systems that have it but don't need it.
