Hello


I am trying to compile some unix code on cygwin, using gcc version:

*****************************************
Reading specs from /usr/lib/gcc/i686-pc-cygwin/3.4.4/specs
Configured with:
/usr/build/package/orig/test.respin/gcc-3.4.4-3/configure --ver

Thread model: posix
gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

*****************************************

and I get these errors:

*****************************************
/home/user/proj/main.c:907: undefined reference to `_sqrtl'
/home/user/proj/main.c:1743: undefined reference to `_powl'
/home/user/proj/main.c:2006: undefined reference to `_ceill'
/home/user/proj/main.c:2035: undefined reference to `_floorl'
*****************************************



Can you please help me find what is missing?

thank you very much, 

Kind Regards,
