I've read the GDB thread you pointed me to, in the meantime.  They suspect
that a *very* recent change in gcc:

2000-02-17  Mark Mitchell  <mark AT codesourcery DOT com>

        * function.c (thread_prologue_and_epilogue_insns): Put a line note
        after the prologue.

has broken the GDB testsuite. 

I think that change tries to work around the bug we've been talking about,
here: that there currently is no .ln between the prologue and the 'real'
code of the function. Seems it's outputting the wrong line number (of the
opening brace, instead of the first line of active code), confusing the
GDB test scripts.

I'll put a mail to the gdb mailing list, describing my results.
