Comment (by rhaas):

 Well yes, it is part of autoconf's AC_INLINE macro. That macro however
 checked for any kind of inline keyword and not just a particular one that
 makes the inline function externally visible (ie. CCTK_CHECK_C_INLINE
 checks for GNU's inline semantics whereas AC_INLINE checked for any inline
 keyword). So it would never define away inline even though the compiler
 does indeed support inline functions :-)

 Any solution that lets me compile is fine with me though.

 I attach a patch for cctk.h and aclocal.m4.

 This still leaves the pgi compiler out in the cold though since I do not
 know how to make it use the gnu inline semantics. Any help is welcome
 given that pgi was the compiler I'd originally like to get to work.
