bison-2.0a feedback

[Bruno Haible]

Some test results of bison-2.0a.


1) On BeOS 5, i586-pc-beos, we have the following warnings.

gcc -Wall -DHAVE_CONFIG_H -I. -I. -I..   -I/boot/home/config/include  -g -O2 -c

The testsuite passes OK.


2) On FreeBSD 4.0, i386, with gcc-2.95.3, we have the following warnings.

gcc -Wall -DHAVE_CONFIG_H -I. -I. -I..   -I/home/bruno/include  -g -O2 -c

scan-skel.l:44: warning: `lineno' might be used uninitialized in this function

The testsuite passes OK.


3) On MacOS X 10.3.9, we have this warning.

if gcc -Wall -DHAVE_CONFIG_H -I. -I. -I..   
-I/Volumes/UserData/local-macos/include  -g -O2 -MT bitset.o -MD -MP -MF 
".deps/bitset.Tpo" -c -o bitset.o bitset.c; \
then mv -f ".deps/bitset.Tpo" ".deps/bitset.Po"; else rm -f ".deps/bitset.Tpo"; 
exit 1; fi
bitset.c: In function `bitset_print':
bitset.c:310: warning: int format, bitset_bindex arg (arg 3)

The testsuite passes OK.


4) With gcc-4.0.0, both on Linux/x86 and MacOS X 10.3.9, the five
"User Actions" tests are skipped. Since gcc-4 will soon be the standard
compiler on these systems, it's worth fixing this.

        * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
        error message syntax used by gcc-4.0.
