I've imported an existing Arduino project (which compiled and ran fine from teh Arduino IDE) but teh .vsarduino.h file which is automatically created in Visual Studio contains spurious lines amongst the function prototypes which I think is confusing the compiler causing several "expected unqualified-id before 'else'" errors. 

The offending lines are of the form "else if ..." and have clearly been extracted from the source .pde files amongst the functions - as if the scope of the real functions wasn't being tracked correctly from the braces '{' & '}'.


Any suggestion as to what is wrong and what to try next please?

I've emailed the source to you, please let me know if you got it?  No problem posting it here if necessary, other than size, as it has already been made open source at http://ardunxt.googlecode.com/svn/trunk.

It appears  this is still a problem. Simple code such as the below will not compile, as the "else if" instruction is interpreted as a new function and copied into the x.vsarduino.h header file.

void setup()
{}

void loop()
{}

int bill(void)
{
     if(1)
     {}
     else if (4)
     {}
     return 1;
}

Here is the x.vsarduion.h file
#define __AVR_ATmega2560__
#define __cplusplus
#define __builtin_va_list int
#define __attribute__(x)
#define __inline__
#define __asm__(x)
extern "C" void __cxa_pure_virtual() {}
void setup();
void loop();
int bill(void);
else if (4);

any ideas??
