Thank you very much for reporting this. The link failure can already be observed
with gperf's own testsuite:
$ export CC="gcc -std=gnu99"
$ export CXX=g++
$ ./configure
...
$ make
...
$ make check
...
gcc -std=gnu99 -g -O2 -o cout cinset.c test.o
cinset.c: In function 'in_word_set':
cinset.c:107: warning: 'hash' is static but used in inline function
'in_word_set' which is not static
test.o: In function `main':
./test.c:31: undefined reference to `in_word_set'
collect2: ld returned 1 exit status
make[1]: *** [check-link-c] Error 1
I'm applying this fix.
2007-03-31 Bruno Haible <address@hidden>
* src/output.cc (Output::output_lookup_function): Emit an inline
marker that also works with gcc-4.3 in c99 or gnu99 mode.
* tests/c-parse.exp, tests/charsets.exp, tests/chill.exp,
tests/cplusplus.exp, tests/gpc.exp, tests/incomplete.exp,
tests/java.exp, tests/languages.exp, tests/modula2.exp,
tests/objc.exp, tests/permut2.exp, tests/permut3.exp,
tests/permutc2.exp, tests/test-4.exp: Update.
