[ECOS] include file incompatibilities...

[Andrew Lunn]

I just found a problem compiling anoncvs for ebsa with the new_net
template.



arm-elf-gcc -c  -I/export/home/lunn/ecos-work-uts/install/include -I/usr/local/pkg/plcuts/ecoscvs/packages/net/common/current -I/usr/local/pkg/plcuts/ecoscvs/packages/net/common/current/src -I/usr/local/pkg/plcuts/ecoscvs/packages/net/common/current/tests -I. -I/usr/local/pkg/plcuts/ecoscvs/packages/net/common/current/src/ -mcpu=strongarm -Wall -Wpointer-arith -Wstrict-prototypes -Winline -Wundef -Woverloaded-virtual -g -O2 -ffunction-sections -fdata-sections -fno-rtti -fno-exceptions -fvtable-gc -finit-priority -D_KERNEL -D__ECOS -D__INSIDE_NET -Wp,-MD,src/inet_ntop.tmp -o src/net_common_inet_ntop.o /usr/local/pkg/plcuts/ecoscvs/packages/net/common/current/src/inet_ntop.c

The problem is that inet_ntop.c include sys/param.h. That has 

// Function mapping
#define printf     diag_printf
#define snprintf   diag_snprintf

later on inet_ntop.c include stdio.h, which has 

// Other non-ISO C functions

externC int
fnprintf( FILE * /* stream */, size_t /* length */,
          const char * /* format */, ... ) CYGBLD_ATTRIB_PRINTF_FORMAT(3, 4);

externC int
snprintf( char * /* str */, size_t /* length */, const char * /* format */,
          ... ) CYGBLD_ATTRIB_PRINTF_FORMAT(3, 4);

Now cyg/infra/cyg_type.h defines

// Teach compiler how to check format of printf-like functions
# define CYGBLD_ATTRIB_PRINTF_FORMAT(__format__, __args__) \
        __attribute__((format (printf, __format__, __args__)))

CPP is changing the printf above into a diag_print because of the
#define in sys/param.h.

Anybody have some goods on how to fix this? I don't like these
#defines in sys/param.h.
