I entertained myself by compiling QEMU with -std=c99 -pedantic and
fixing some issues found with that.
v1->v2:
Fix copypasta in 1/5 (Anders Schwab)
Resent with correct address
Blue Swirl (5):
Avoid GCC extension ?:
Avoid returning void
Use __asm__ instead of asm or __asm
Avoid unportable %m format
Avoid redefining inline

Replace expr1 ?: expr2 with expr1 ? expr1 : expr2 as K&R intended.
If expr1 has side effects, introduce a temporary variable.
