            Bug ID: 3392699
           Summary: having empty define at the end of macro expansion
                    breaks GLOBAL
           Product: NASM
           Version: 2.15 (development)
          Hardware: All
                OS: All

     Obtained from: Build from source archive using configure

The following test case worked in 2.14.02 and in 2.15.02 it produces a warning
and doesn't apply "global" to the symbol (reduced from isa-l_crypto build):

%define FUNCT_EXTENSION

%define FN_NAME(x,y) test_ %+ x %+ _ %+ y %+ FUNCT_EXTENSION

global FN_NAME(foo, bar)
FN_NAME(foo, bar):
        nop
        ret

The warning from 2.15.02:

tc.asm:5: warning: improperly calling multi-line macro `global' with 0
parameters [-w+macro-params-legacy]

[3]     |                   0|                   0|NOTY |LOCL |0    |1     
|test_foo_bar

2.14.02:

[3]     |                   0|                   0|NOTY |GLOB |0    |1
