Yes, but rsxntdj seems to link with its own libc.

Here you are:

1) Output with the -v switch:

gcc -v -Zwin32   parserad.o flexrad.o artist.o windecod.o  -o

flexrad.o: In function `yy_get_next_buffer':
flexrad.c:286: undefined reference to `_getc_inline'

flexrad.c:287: undefined reference to `ferror'
flexrad.o: In function `yy_init_buffer':
flexrad.c:640: undefined reference to `fileno'


2) I have some problems with the line numbers above mentionned: 

According to my flexrad.c file, yy_get_next_buffer begins at line 836
and yy_init_buffer at line 1265 (strange, isn't it ?)

However, here are the lines 278 to 296 from my flexrad.c file:

278: #define YY_DO_BEFORE_ACTION \
279: 	yytext_ptr = yy_bp; \
280:	yyleng = (int) (yy_cp - yy_bp); \
281:	yy_hold_char = *yy_cp; \
282:	*yy_cp = '\0'; \
283:	yy_c_buf_p = yy_cp;
284:
285: #define YY_NUM_RULES 12
286: #define YY_END_OF_BUFFER 13
287: static yyconst short int yy_accept[35] =
288:    {   0,
289:        0,    0,    4,    4,   13,   11,    9,    8,   10,   11,
290:       11,    2,    4,    4,    6,    4,    5,    4,    4,    2,
291:        9,    3,    0,    4,    4,    5,    5,    7,    4,    0,
292:        4,    1,    1,    0
293:    } ;
294: 
295: static yyconst int yy_ec[256] =
296:     {   0,

If that can help, here is flexrad.l which gives flexrad.c with:
flex -t flexrad.l > flexrad.c (I use flex 2.5.4)
