Valid test case with global of $-prefixed label produces "error: identifier expected after global,"

[ecm-pushbx]

Recent NASM versions give multiple errors assembling display.nas of my MS-DOS v4.01 format.exe port, like "error: identifier expected after global, got ..." where the "got" string appears to be a valid identifier. An older NASM version works fine with the same sources.

The NASM commit IDs in the following test run are specified in the directory names:

0349069 works.

ac0429f (fixed revision for the #206 issue) fails, as do 1e494b4 (latest git) and 755593b (my current "good" revision).

The test case is available in https://pushbx.org/ecm/test/20260329/ as well as https://hg.pushbx.org/ecm/testnas1

I reduced the test case to three lines:

section code

%idefine PUBLIC global

PUBLIC $M_CLS_1

[ecm-pushbx]

2 lines:

section code

global $M_CLS_1

Assemble with -f obj

Worked around by dropping the dollar signs: https://hg.pushbx.org/ecm/msdos4/rev/873d07156c0c

A fix for #223 was checked in, it should fix this as well.
