2 compilation bugs

[Pascal Maillard]

Hi folks!

I encountered 2 bugs during compilation of lilypond 1.8.1.

I've got an x86 machine running under SuSE Linux 8.2 (kernel 2.4.20). My glibc 
is version 2.3.2.

gcc -v says this:
Reading specs from /usr/lib/gcc-lib/i486-suse-linux/3.3/specs
Configured with: ../configure --enable-threads=posix --prefix=/usr 
--with-local-prefix=/usr/local --infodir=/usr/share/info 
--mandir=/usr/share/man --libdir=/usr/lib 
--enable-languages=c,c++,f77,objc,java,ada --disable-checking --enable-libgcj 
--with-gxx-include-dir=/usr/include/g++ --with-slibdir=/lib 
--with-system-zlib --enable-shared --enable-__cxa_atexit i486-suse-linux
Thread model: posix
gcc version 3.3 20030226 (prerelease) (SuSE Linux)

My flex version is 2.5.4a, my bison version is 1.75.

The bugs:
1.) configure didn't detect that my glibc had the functions snprintf and 
vsnprintf. I had to change the values in config.h manually

2.) I got the follwing warnings / errors during compilation of the 
lexer/parser:

I read what you wrote about flex conflicting with gcc-3.1.1 but the changes 
lexer-gcc-3.1.sh does to FlexLexer.h had already been applied to my 
FlexLexer.h, so this should not be the problem. I also fixed lexer.cc this 
way, but this didn't work either.

Hope this could help you and I wish you happy coding,
