Bug#953815: libc6-dev: Cannot build GNU Emacs - limits.h error in configure
Package: libc6-dev
Version: 2.30-2
Severity: normal
Dear Maintainer,
I cannot build GNU Emacs on Debian unstable after the latest update - configure
fails with an error with the limits.h include.
Here is a minimal reproduction:
$ cat test.c
#include <stdlib.h>
#include <limits.h>
int main(void) {
exit(0);
}
$ gcc -Wall test.c
In file included from test.c:2:
/usr/include/limits.h:124:26: error: no include path in which to search for limits.h
124 | # include_next <limits.h>
| ^
$
On Debian stable the example program compiles without problem.
For completeness, here are the errors from the config.log produced by GNU Emacs'
configure:
