missing include in modules/pam_namespace/pam_namespace.c

[jhheider]

modules/pam_namespace/pam_namespace.c makes use of SIZE_MAX but doesn't include stdint.h; resulting in build failures on 1.6.0.

pam_namespace.c: In function 'process_line':
pam_namespace.c:649:41: error: 'SIZE_MAX' undeclared (first use in this function)
  649 |         if (count > UINT_MAX || count > SIZE_MAX / sizeof(uid_t)) {
      |                                         ^~~~~~~~
pam_namespace.c:41:1: note: 'SIZE_MAX' is defined in header '<stdint.h>'; did you forget to '#include <stdint.h>'?
   40 | #include "argv_parse.h"

pam_namespace.c:649:41: note: each undeclared identifier is reported only once for each function it appears in
  649 |         if (count > UINT_MAX || count > SIZE_MAX / sizeof(uid_t)) {
      |                                         ^~~~~~~~
make[3]: *** [Makefile:819: pam_namespace.lo] Error 1

the following fixes it:

sed -i -e '/argv_parse\.h/a\
#include <stdint.h>\
' modules/pam_namespace/pam_namespace.c
