gcc & linker question (Solaris 10)

Hi,

I'm confused about the GCC & Linking process could somebody please briefly explain?

I have GCC 3.4.6 installed from SunFreeware. Reading the narrative alongside the package states "It was compiled to use the SUN assembler and loader usually in /usr/ccs/bin if the SUNW developer packages are installed."

SUNW developer packaes are installed and ld / as / ar are in the relevant /usr/ccs/bin directory.

I also have the GNUbinutils package installed which installs ld / as / ar in /usr/local/bin. this /usr/local/bin dir precedes / usr/ccs/bin in my $PATH.

When installing third party applications, i commonly see:
./configure \
--with-gnu-ld \
--with-gnu-as \
which i specify & the applications install and work okay, however:

checking config.log shows

Reading specs from /usr/local/lib etc etc etc
Configure with: ../configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin

whats going on?

Thanks

Nick

lint(1B)                                             SunOS/BSD Compatibility Package Commands                                             lint(1B)

NAME
lint - C program verifier SYNOPSIS
/usr/ucb/lint [options] DESCRIPTION
/usr/ucb/lint is the interface to the BSD Compatibility Package C program verifier. It is a script that looks for the link /usr/ccs/bin/ucblint to the C program verifier. /usr/ccs/bin/ucblint is available only with the SPROcc package, whose default location is /opt/SUNWspro. /usr/ucb/lint is identical to /usr/ccs/bin/ucblint, except that BSD headers are used and BSD libraries are linked before base libraries. The /opt/SUNWspro/man/man1/lint.1 man page is available only with the SPROcc package. OPTIONS
/usr/ucb/lint accepts the same options as /usr/ccs/bin/ucblint, with the following exceptions: -Idir Search dir for included files whose names do not begin with a slash (/) prior to searching the usual directories. The directories for multiple -I options are searched in the order specified. The preprocessor first searches for #include files in the directory containing sourcefile, and then in directories named with -I options (if any), then /usr/ucbinclude, and finally, in /usr/include. -Ldir Add dir to the list of directories searched for libraries by /usr/ccs/bin/ucblint. This option is passed to /usr/ccs/bin/ld. Directories specified with this option are searched before /usr/ucblib and /usr/lib. -Y P, dir Change the default directory used for finding libraries. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
/usr/lint/bin/ld link editor /usr/lib/libc C library /usr/ucbinclude BSD Compatibility directory for header files /usr/ucblib BSD Compatibility directory for libraries /usr/ucblib/libucb BSD Compatibility C library /usr/lib/libsocket library containing socket routines /usr/lib/libnsl library containing network functions /usr/lib/libelf library containing routines to process ELF object files /usr/lib/libaio library containing asynchronous I/O routines ATTRIBUTES
