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'". -- snap -- Hmm?As to the first one, I think your problem description is clear (the problem is clear without being explained to begin with) but "there is no danger of that now" is somewhere between a lame excuse for not doing it the right way and a bug waiting to happen. If "value computed is not used" is the issue, why doesn't this work? #define ensure_initialization() (void)(mparams.magic != 0 || init_mparams())
That works.
As to the second one, I think you lost "even if we happen to" part (that logically corresponds to "... that is why we do not want to limit the inclusion to !__MINGW32__ case") from the description, making it less readable...
You mean "even if we happen to be on Windows"? Fine with me. Want me to resend a fixed patch? Ciao, Dscho
