I tried to compile on Linux, got this:

[matt at localhost Allan]$ make
Makefile:9: *** missing separator.  Stop.

I removed the last line in the Make file and got this:

[matt at localhost Allan]$ make
cc -g -Wall -static    allan.c   -o allan
allan.c:19:27: floatingpoint.h: No such file or directory
allan.c: In function `main':
allan.c:722: warning: implicit declaration of function `fpsetmask'
allan.c:722: error: `FP_X_UFL' undeclared (first use in this function)
allan.c:722: error: (Each undeclared identifier is reported only once
allan.c:722: error: for each function it appears in.)
make: *** [allan] Error 1

Looks like I'm missing floatingpoint.h.  A BSD thing?
