Subject: libctf: check for vasprintf
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=43a61d7d3e619385b98c03d43733572b5b1dc015;p=binutils-gdb.git

libctf: check for vasprintf

We've been using this for all of libctf's history in binutils: we should
check for it in configure.

libctf/
	configure.ac: Check for vasprintf.
	configure: Regenerated.
	config.h.in: Likewise.
