M4 Maintainers:
I work on a test system for distro testing. I need to build newer Fedora
images
before they are released to public. A change that was introduced is the
#define SIGSTKSZ is no longer a statically defined variable. It's value can
only be determined at run time.
# define SIGSTKSZ sysconf (_SC_SIGSTKSZ)
This affects m4 code since the code assumes a statically defined variable
which
can be determined at preprocessor time. As a result, the m4 code no longer
compiles.
/usr/include/signal.h:315,
from ./signal.h:52,
from c-stack.c:49:
c-stack.c:55:26: error: missing binary operator before token "("
55 | #elif HAVE_LIBSIGSEGV && SIGSTKSZ < 16384
| ^~~~~~~~
I am using m4-1.4.18 with compiler gcc (GCC) 10.2.1 20201125 (Red Hat
10.2.1-9).
Please advise how I can get past this. It doesn't look like a simple
change. Do you
already have a patch available for this?
Carol
