Summary: SDCC shows wrong line number in warning 94

Initial Comment:
1: Sample code that reproduces the problem.

Source file is attached.

2: Exact command used to run SDCC on this sample code

sdcc -mz80 --code-loc 26000 --data-loc 0xF800 --no-std-crt0 --opt-code-size --max-allocs-per-node 1 --funsigned-char --disable-warning 85 -L z80 Basic.c

3: SDCC version tested (type "sdcc -v" to find it)
SDCC : mcs51/gbz80/z80/ds390/pic16/pic14/TININative/ds400/hc08 3.0.4 #6849 (Sep 13 2011) (MINGW32)

It is old problem. It present in old SDCC versions, for example, in SDCC 3.0.4 #6712 (MINGW32), and also it is in new build too.

4: Copy of the error message or incorrect output, or a clear description of the observed versus expected behavior.

Compiler shows:
Basic.c:62: warning 94: comparison is always true due to limited range of data type

but real line number of warning 94 is not 62, but 70. This is a special event when number of the line shows incorrect. Though if change or remove several unessential lines, that all become it is correct.
