Okay, how about this in the commit body in addition?
-- snip --
Nedmalloc's source code has a cute #define construct to avoid inserting
an if() statement, because that might interact badly with enclosing if()
statements. However, there is no danger of that now, but GCC > 4
complains "warning: value computed is not used".
Also, with the version of MinGW's headers in msysGit, we need to include
malloc.h lest the compiler complain about an "incompatible implicit
declaration of built-in function 'alloca'".

Hmm?
