problem while linking with -mno-cygwin

[Guglielmo Pasa]

While trying to build an app I have a problem on linking.
I get:

/tmp\ccelshwp.o(.text+0x51):gaussj.c: undefined reference to
`_impure_ptr'
/tmp\ccelshwp.o(.text+0x6b):gaussj.c: undefined reference to
`_impure_ptr'
/tmp\ccelshwp.o(.text+0x81):gaussj.c: undefined reference to
`_impure_ptr'
collect2: ld returned 1 exit status

Do I miss some lib to link with ?
