When building frysk without --enable-coverage (compilation and link options
include -g -O), funit-scopes.c compiles and links correctly.

When building frysk with --enable-coverage (compilation and link options include
-g --coverage --O0), funit-scopes.c compiles correctly, but fails to link with
the following error:

gcc
-I/home/aedil/build_farm/frysk_gcov/frysk_config/frysk-core/../frysk-imports/include
-I/home/aedil/build_farm/frysk_gcov/frysk_config/frysk-core -I. -fPIC
-fasynchronous-unwind-tables  -g  --coverage -O0 -Wall -Werror   -o
frysk/pkglibdir/funit-scopes  frysk/pkglibdir/funit-scopes.o  
frysk/pkglibdir/funit-scopes.o: In function `first':
/home/aedil/build_farm/frysk_gcov/frysk_config/frysk-core/frysk/pkglibdir/funit-scopes.c:13:
undefined reference to `second'
collect2: ld returned 1 exit status
make[2]: *** [frysk/pkglibdir/funit-scopes] Error 1

This is happening on FC6, both on i386 and x86_64.
Gcc version is gcc version 4.1.1 20070105 (Red Hat 4.1.1-51).

The only change between a previous successful build of frysk and the current
failures (as far as this file is concerned) is the actual content of the source
code file (same GCC versions etc).

Investigating this problem a bit further, but it seems to be a bug in gcc.
