It is also possible to pass --print-prog-name=ld to gcc. Here's some 
results for you to compare.

Solaris:
$ gcc --print-prog-name=ld
/usr/ccs/bin/ld
$ `gcc --print-prog-name=ld` -V
ld: Software Generation Utilities - Solaris Link Editors: 5.8-1.279

Cygwin:
$ gcc --print-prog-name=ld
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../../i686-pc-cygwin/bin/ld.exe
$ `gcc --print-prog-name=ld` -V
GNU ld version 2.14.90 20030901
Supported emulations:
i386pe

Linux:
$ gcc --print-prog-name=ld
/usr/lib/gcc-lib/i586-suse-linux/3.3.1/../../../../i586-suse-linux/bin/ld
$ `gcc --print-prog-name=ld` -V
GNU ld version 2.14.90.0.5 20030722 (SuSE Linux)
