The gcc14 machine has a moderately old host gcc, which was causing a recurrent build failure of host-lttng-babeltrace: http://autobuild.buildroot.org/results/492/49216052c161874f41738e41e6e0c89a6dd04000/build-end.log This commit adds a patch to fix this build failure, related to the access of the ULLONG_MAX define on compilers that did not default to the C99 variant of the C language.

Support old compilers
|
|
|
|
Some old compilers do not use C99 as their default C language variant,
|
|
for example gcc 4.3.x, which is used on some old machines. When such a
|
|
compiler is used, by default, ULLONG_MAX is not visible. Adding
|
|
-std=gnu99 is needed to make this definition visible.
|
|
|
|
In autoconf speak, this translates into the need of using
|
|
AC_PROC_CC_STDC instead of AC_PROG_CC. See
|
|
http://www.gnu.org/software/autoconf/manual/autoconf-2.65/html_node/C-Compiler.html
|
|
for more details.
