[avr-gcc-list] Converting from IAR to avr-gcc

[Gregory Berardi]

I am converting a very large program for the atmega128 from IAR to
avr-gcc and I'm having some problems.  Once I get this to compile and
work I want to convert it to atmega103 since the 128 is obsolete.  We
are currently building boards with the 128 until we run out, sometime in
Februrary or March.  My current problem is a function that takes a float
and returns a float.  The header prototype is;

float AdjFZSP(float SP);

I get and error of;

parse error before '(' token

Can't I have a return type float?

Could someone show me a way to get around this?

Is there some information on converting from IAR to avr-gcc?
