Samba 3.5.6 and determining ld version

[Thomas Bork]

Hi @all,

in Samba 3.5.6 was a change in configure.in in determining the gnu ld 
version (my old Samba version was 3.4.9 and was ok):

New version:
ac_cv_gnu_ld_version=`$CC -Wl,-v /dev/null 2>/dev/null | head -1`

Old version was:
ac_cv_gnu_ld_version=`$LD -v 2>/dev/null | head -1`

deveis # gcc -Wl,-v
collect2 version 3.4.6 (i386 Linux/ELF)
/usr/bin/ld --eh-frame-hdr -m elf_i386 -dynamic-linker 
/lib/ld-linux.so.2 /usr/lib/gcc/i486-pc-linux-gnu/3.4.6/../../../crt1.o 
/usr/lib/gcc/i486-pc-linux-gnu/3.4.6/../../../crti.o 
/usr/lib/gcc/i486-pc-linux-gnu/3.4.6/crtbegin.o 
-L/usr/lib/gcc/i486-pc-linux-gnu/3.4.6

/usr/lib/gcc/i486-pc-linux-gnu/3.4.6/../../../crtn.o
/usr/lib/gcc/i486-pc-linux-gnu/3.4.6/../../../crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
GNU ld version 2.17
deveis # gcc -Wl,-v /dev/null 2>/dev/null
deveis #ld -v 2>/dev/null | head -1
GNU ld version 2.17


Thats why I have this in configure:
checking if the linker used by compiler is GNU ld... yes
checking GNU ld release date...
checking GNU ld release version...
checking GNU ld release version major...
checking GNU ld release version minor...
./configure: line 11878: test: : integer expression expected
./configure: line 11878: test: : integer expression expected
./configure: line 11881: test: : integer expression expected

The old version was ok for me...
