Apparently not (cf. below).

Yes, you are using the wrong compiler.

Don't! This is plain wrong.

gcc is supposed to be the native CC, while i386-rtems-gcc is supposed
the target's cross-compiler.

Well, .. no. 

What might happen, is the native compiler not choking during compilation
of target code, because you probably are using an i386-based native tool
chain, but that's all.

???

PATH=/opt/rtems/bin:$PATH

Neither /opt/rtems nor any other directory from below /opt/rtems are
supposed to be in $PATH.

I'd guess, having started to configure without /opt/rtems/bin in $PATH
and then later having put /opt/rtems/bin in $PATH is the cause.

(config.cache etc. containing the old (bogus) compiler)

Are you using Cygwin? Then, there are other possible causes for your
problems.

This is the native CC, not the target's CC => Something is broken w/
your installation or you "playing with paths" is interferring".

Try to start from scratch:

Start a new shell, then
export PATH=/opt/rtems/bin:$PATH
mkdir build
cd build
<pathtortems>/configure --target=i386-rtems [further options]
