variable expansion

gistfile1.txt

glibc has the following line:
#define SYS_ify(syscall_name)   __NR_##syscall_name

So I'm trying to do a similar expansion with "name" below:

# undef PSEUDO
# define PSEUDO(name, syscall_name, args)                                     \
  .data;                                                                      \
##name_jtarget_name: .string "test";                                          \
  .text;                                                                      \
  ENTRY (name)                                                                \
    movl $##name_jtarget_name, %esi;                                          \
    DO_CALL (syscall_name, args);                                             \
    cmpq $-4095, %rax;                                                        \
