I do, on a daily basis.

First reason is that on those (proprietary) OS's there is no (more) update available for the ANSI C89 compiler.

Second reason is that GNU folk do not consider OS's other than Linux worthwhile caring for. E.g. on HP-UX PA-RISC (10.20, 11.00, 11.11 and 11.23) it is impossible to create a GNU gcc-4.x.x that compiles reliable in 64bit mode, so I'm stuck to version 3.4.6.

GNU gcc is a nightmare to compile on e.g. HP-UX 11.23 or 11.31 if all of your system is set up to be 64bitall only. GNU gcc folk claim the compiler just needs a 32bit environment to build a compiler that can generate 32bit and 64bit objects, but in order to get that compiler compiled, you need a 32bit environment and - at current - THREE extra packages installed (gmp, mpfr and mpc) that all need a gcc compiler to get compiled properly -> endless loop of FAIL. On these I stopped porting with gcc-4.2.4.

Third reason is that (maybe because of reason 2), code generated with HP C-ANSI-C compiler runs up to 15% faster than when compiled with GNU gcc, so the option to use a gcc compiler just because it can do C99 is not a very obvious one. I bet inlining functions won't get a 15% speed gain ove macros, but I didn't check that.
