Hi,

This patch is as per suggestion from Pedro, I've also added a check
for vasprintf just for completeness sake, and that there is a similar
condition for HAVE_DECL_VASPRINTF in libiberty.h.

https://sourceware.org/ml/gdb-patches/2015-06/msg00654.html

As per my comments earlier, I am going blind on this, but it looks
correct to me, and I can at least verify on my machine that I can see:

configure stage
---
checking whether asprintf is declared... yes
checking whether vasprintf is declared... yes
---
config.h
---
/* Define to 1 if you have the declaration of `asprintf', and to 0 if you
   don't. */
#define HAVE_DECL_ASPRINTF 1

/* Define to 1 if you have the declaration of `vasprintf', and to 0 if you
   don't. */
#define HAVE_DECL_VASPRINTF 1
---

So should either one be false, they should have a proper declaration
in libiberty.h

Luis, can you check this patch is good for you?


Regards
Iain
