MICRO-C Application and Setup Notes
This archive contains the MICRO-C freeware C compler, written by Dave
Dunfield and a product of Dunfield Development
Systems of Nepean, Ontario, Canada, (613) 256-5820. While MICRO-C is
free, it is not GPL and therefore not officially a part of, but is distributed
as an adjunct to, the FreeDOS operating
system.
MICRO-C is not fully ANSI compliant and does have some quirks you need
to be aware of, due to its origins as a compiler for embedded systems.
These are described in the documentation and in the links below. Please
understand that this does not change the fact that MICRO-C is an
excellent product and is well suited for generating small DOS programs
and utilities on x86 systems. I urge you to give MICRO-C a chance and I
think you will be pleased with the compiler's strengths and capabilities,
especially when compared to other free C compilers.
If you're interested, The MICRO-C library source code can be purchased
from DDS for $25 US / $32.50 Canadian as of this writing.
