ROLF is a GUI framework using the framebuffer device on Linux to provide a look and feel similar to that of the RISC OS operating system. The RISC OS GUI is largely unchanged in concept since the late 1980's, not because of any lack of development, but because it just worked.

knoppix@Microknoppix:/tmp$ gcc x.c -c

I'm a software engineer, currently staying at home (in Germany where I moved in 2000) to look after my two daughters. I started programming in the eighties which might be why I like elegant software which doesn't break and isn't bloated. I still use RISC OS daily for e-mail and Usenet, but have moved over mostly to Linux for web browsing and video. I still find the RISC OS GUI a pleasure to use, and I also admire the Eiffel programming language, although I don't think it has lived up to its initial promise.

It doesn't. siginfo is a POSIX feature, so you should be compiling with -DPOSIX_C_SOURCE=200112L (or similar). GCC enables POSIX features by default, as they're generally useful. Asking for strict C99 compliance will disable GCC's auto-enabling of POSIX extensions.
Ah, OK.
Although -DPOSIX_C_SOURCE=200112L doesn't work (with --std=c99). Nor does -D__USE_POSIX, or -D__USE_POSIX199309.
Or -D_POSIX_C_SOURCE=2 or -D_XOPEN_SOURCE or -D_POSIX_SOURCE.
I'll just use -std=gnu99. :-/
