Compiler warning on Debian/Sparc

Hello ...

I have compiled PostgreSQL on Debian/Woody on a Sparc machine.
Unfortunately there are some nasty looking compiler warnings ...

Here is the code around line 350:
/* Get machine-dependent inline versions (if there are any).  */
#ifdef __USE_EXTERN_INLINES
# include <bits/mathinline.h>
#endif


Maybe this is helpful.
