Re: how to exclue libm when compile C++ program with g++

[nospam]

because for some ARM platform, there is no floating point co-prosessor
and the floationg are emulated by software and is extremely slow.

there are quite a lot of project are like that:
for example
- libmad is a integer only decoder for mp3
- libjpeg is a integer only decoder for jpeg
- libmpeg4
- also the invention of H.264 relies only on integer!
