SoftFloat as written requires an ISO/ANSI-style C compiler. No attempt has

style'' compilers are not adequate for compiling SoftFloat. All testing I
have done so far has been with the GNU C Compiler. Compilation with other
compilers should be possible but has not been tested.

SoftFloat is written in C and is designed to work with other C code. The
SoftFloat header files assume an ISO/ANSI-style C compiler. No attempt

particular, the distributed header files will not be acceptable to any
compiler that does not recognize function prototypes.
