not fitting into Atmega8 but fits fine into Attiny85.

[positron96]

Hello. I'm trying to compile a program with RF24, RF24Network and RF24Mesh for Atmega8. It is larger that its memory and I get ld.exe: region `text' overflowed by 90 bytes message.

But if I compile for attiny85 (using https://github.com/SpenceKonde/ATTinyCore), the firmware fits totally fine and I get Sketch uses 6318 bytes (77%) of program storage space. Maximum is 8192 message.

Can I get the same size for Atmega8?

I've noticed that RF24 uses special SPI code for Attiny's (which seems to be software bitbanging) while Megas use generic SPI library. Is this the only cause for size increase? Can I tweak defines to use ttiny's software SPI in atmega?
