Package: libc6-dev
Version: 2.10.2-9
Severity: normal
I try to compile this:
#include <stdlib.h>
int main () {
putenv("a=b");
}
And i point out that the include is there as reported by putenv(3) manpage.
But compiling it with:
$ gcc -std=c99 test.c
I obtain:
test.c: In function ‘main’:
test.c:4: warning: implicit declaration of function ‘putenv’
I don't think this is right
Bye

It is, the manpage also says:
| Feature Test Macro Requirements for glibc (see
| feature_test_macros(7)):
|
| putenv(): _SVID_SOURCE || _XOPEN_SOURCE
As a consequence you should compile your file with -D_XOPEN_SOURCE or
-D_SVID_SOURCE.
