This is caused by the change in the build system. At one time stdint  
or sys/types.h were always included by chicken.h, now only when 64- 
bit cpu target. Further, the defines, such as HAVE_STDINT_H, were  
always available from chicken.h, now only if HAVE_CONFIG_H or  
HAVE_CHICKEN_CONFIG_H are defined when compiling.

I suspect you have a 64-bit cpu, so stdint.h is included by  
chicken.h, but, since chicken-config.h is not automatically included  
by chicken.h when compiling mathh-int.c it doesn't know that  
HAVE_STDINT_H is true, so it includes sys/types.h & thus "conflicting  
types"

Be nice if the eggs could rely on the config machinery like before. &  
why stdint.h or sys/types.h is only included for a 64-bit cpu is a  
little odd.

Please wait for a day, some consultation is needed.

Sorry,
Kon
