BUG? Inlined function generates error message

[Johann Klammer]

Hello,

I was trying to recompile icarus verilog on my box, and ran into this 
rather strange bug.

<http://members.aon.at/~aklamme4/scratch/gcc_fail.tbz>

This contains two .cc files and one script that compiles(ignore the 
warnings) and links them. When linking it complains:

/./gcc_a.cc:23: undefined reference to `check_identifier(char const*, 
unsigned int)'
collect2: error: ld returned 1 exit status

The function is there but declared with:

#ifdef __GNUC__
__inline
#if defined __GNUC_STDC_INLINE__ || defined __GNUC_GNU_INLINE__
__attribute__ ((__gnu_inline__))
#endif
#endif
const struct lexor_keyword *
...

It does not get called from outside...

-rdynamic and -ldl do not seem to change things

Versions:

$ dpkg -l binutils gcc

(on a debian testing)

The code fragment is from a gperf generated file....

What to do?
