(glibc-2.1.3 here)

actually, diference is both pthread and glibc export fork() as weak symbols
which means compile order is used, while system() only exists in glibc,
i think :)

also,

chbm@whisky:~ cc atfork-test.c  -lglib -lgthread
chbm@whisky:~ ldd a.out 
	libglib-1.2.so.0 => /usr/lib/libglib-1.2.so.0 (0x4001d000)
	libgthread-1.2.so.0 => /usr/lib/libgthread-1.2.so.0 (0x4003e000)
	libc.so.6 => /lib/libc.so.6 (0x40041000)
	libpthread.so.0 => /lib/libpthread.so.0 (0x40136000)
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
chbm@whisky:~ cc atfork-test.c -lpthread -lglib -lgthread
chbm@whisky:~ ldd a.out
	libpthread.so.0 => /lib/libpthread.so.0 (0x4001d000)
	libglib-1.2.so.0 => /usr/lib/libglib-1.2.so.0 (0x40030000)
	libgthread-1.2.so.0 => /usr/lib/libgthread-1.2.so.0 (0x40051000)

	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

how the link order of the first is messed up, fork() from libc is used
while in the 2nd fork() from libpthread is used. 

this is of course, a glibc 'issue'.

i gota test this in debian/unstable as they have glibc > 2.2.2 which 
aparently have some symbols demangled
