Package: autoconf
Version: 2.69-2
Severity: minor
A developer may want to test his software with
-Werror=old-style-definition (in particular because such definitions
could be a real bug in the software). But configure fails because
autoconf generates such a function definition. For instance:
[...]
configure:4069: checking whether the C compiler works
configure:4130: gcc -O2 -Wall -Wold-style-declaration -Wold-style-definition
-Wmissing-parameter-type -Wmissing-prototypes -Wmissing-declarations
-Wmissing-field-initializers -Werror conftest.c >&5
conftest.c: In function 'main':
conftest.c:12:1: error: old-style function definition
[-Werror=old-style-definition]
main ()

cc1: all warnings being treated as errors
configure:4130: $? = 1
configure:4144: result: no
configure: failed program was:

| }
configure:4144: error: in `/home/vlefevre/software/mpfr':
configure:4144: error: C compiler cannot create executables
See `config.log' for more details
[...]
Are there still compilers that fail on "int main(void) { ... }"?
In any case, certainly not when the compiler has been recognized
as gcc (like here).
