When I try to compile the new C99 runtime on my Solaris machine, I get the following errors platform.h:34:18: fenv.h: No such file or directory platform.h:35:20: stdint.h: No such file or directory Any pointers on what magic defines will fix things? My machine's uname -a reports SunOS blade 5.8 Generic_108528-09 sun4u sparc SUNW,Sun-Blade-100
