cyrus-imapd 2.1.13 built with gcc 3.3 on linux (redhat)?

[Will Partain]

Folks, has anyone built cyrus-imapd 2.1.13 with gcc 3.3 on
linux (redhat)?  I am getting odd compile errors, using a
process of long standing... maybe something is wedged
here...

The root of it seems to be that my gcc 3.3 doesn't #define
__STDC__; consider, for gcc 3.3:

   % gcc --use-version=3.3 -E -dM hello.c |grep STDC
   #define __STDC_IEC_559_COMPLEX__ 1
   #define __STDC_HOSTED__ 1
   #define __STDC_IEC_559__ 1
   #define __STDC_ISO_10646__ 200009L

[yes, 'gcc' is a script that interprets that --use-version]

whereas for a previous version:

   % gcc --use-version=3.2.2 -E -dM hello.c |grep STDC
   #define __STDC_IEC_559_COMPLEX__ 1
   #define __STDC_HOSTED__ 1
   #define __STDC_IEC_559__ 1
   #define __STDC_ISO_10646__ 200009L
   #define __STDC__ 1

As the cyrus-imapd code keys off of __STDC__, things go
wonky pretty fast.  Any ideas/info welcome.

  printf("hello, world!\n");
