Line 1:
Smaller C is a simple and small single-pass C compiler, currently supporting most of the C language common between C89/ANSI C and C99 (minus some C89 and plus some C99 features).
 
The compiler self-hosts on DOS, Windows, Linux and Linux,Mac OS X meaning it can compile under and for all threefour OSes and it may additionally be used to write bootloaders and other parts OS running in [[Real Mode]], [[Virtual 8086 Mode]], [[Unreal Mode]] and 32-bit [[Protected Mode]].
 
With some work you may even be able to run Smaller C in your OS (e.g. you need to port [[NASM]]/[[YASM]] or [[FASM]] (FASM is probably easier) to your OS and make appropriate changes in the Smaller C standard library to use your OS system calls instead of those for DOS, Windows and, Linux or Mac OS X).
 
The core compiler comes with a preprocessor, a linker and a compiler driver (the driver invokes the preproccessor, the core compiler, the assembler, and the linker and supports options similar to those of [[GCC]]). The linker ([[smlrl]]) can produce the following executable formats: [[COM]], [[MZ]], [[PE]], [[ELF]], [[MACH-O]], [[A.out]] and flat executables. Btw, [[COM]] and [[MZ]] may be booted directly with [[BootProg]].
