I am trying to compile DBD-Informix-1.04.PC1 on an SGI using gcc and here are the errors when I try.
Could someone please help me? Thank you in advance.

I don't understand all the misspellings, but we can probably assume that was something to do with cut'n'paste going awry.
Judging from the error messages, the ESQL/C for SGI is configured with rather a lot of options that are specific to the native (non-gcc) compiler, and you will need to do some work to get this to compile with gcc. What you want is the analog of the Solaris::GCC module for SGI/Irix. However, you can do quite a lot with DBD::Informix. You'll probably want to set the environment with:
DBD_INFORMIX_DEBUG_ESQLTEST=1
DBD_INFORMIX_DEBUG_ESQLCC=1
DBD_INFORMIX_DEBUG_ESQLLD=1
INFORMIXC='gcc -g'
In due course, you will probably want to set these too:
DBD_INFORMIX_ESQLCC_REMOVE_OPTIONS_REGEX
DBD_INFORMIX_ESQLLD_REMOVE_OPTIONS_REGEX
For example, since -n32 is giving grief, you might set these to:
s/^-n32$//
More likely, we have more work to do, and your final REGEX values will be considerably more complex. Fortunately, you can probably do it in Perl. You can find more information on the available environment variables in the originally named file - Notes/environment.variables.
Alternatively, you can actually hack your esql script (after making a backup of the original version); that might be simpler in the long run, especially if you need to add flags as well as remove them. You can often add the flags in the base value of INFORMIXC - as shown above. Sometimes, this is inadequate, and then hacking the ESQL/C compiler (esql script) is best. You can also simply test this by compiling the esqlbasic.ec program:
esql -o esqlbasic esqlbasic.ec
It is provided to help people deal with such eventualities.
Alternatively again, if you've been using ESQL/C to build programs quite happily, then you can think about rebuilding Perl with the native C compiler and then using that to build all your Perl modules. Depending on how much stuff you have installed, this may or may not be simpler -- it usually isn't, but in this case, it might be a close call.
Good luck, and keep me posted.
