Hi,
Why does the compilation of b.c fail, while that of a.c succeeds with
gcc-4.0.0 or later? Compilaton with gcc-3.4.4 both failed.
% gcc -v
Using built-in specs.
Target: sparc-sun-solaris2.9
Configured with: ../gcc/configure --disable-nls --with-gmp=/usr/local --with-mpfr=/usr/local
Thread model: posix
gcc version 4.0.2 20050707 (prerelease)
% gcc a.c
% gcc b.c
Undefined first referenced
symbol in file
isinf /tmp/ccSOxuGb.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status
