Using Microchip source code

[SeeCwriter]

I am interested in using a C source file from Microchip to implement a TCP/IP stack. Their app note says it's written for the C18 and Hi-Tech PICC 18 compilers. I'm guessing that these compilers are case sensitive, as every other C compiler in the world is, except for CCS. Am I asking for trouble to try to use this C library with CCS? Are there other options I'm not aware of?

I'm guessing that these compilers are case sensitive, as every other C
compiler in the world is, except for CCS.

Download the CCS compiler manual.
http://www.ccsinfo.com/downloads/CReferenceManual.pdf

Look in the Preprocessor Directives section, specifically at
the Compiler control section.

You will find the directive to do what you need.

I know that you can configure the CCS compiler to be case sensitive. But the manual also says that none of the CCS libraries have been tested in case-sensitive mode, so proceed at your own risk. I have no desire to debug CCS's libraries.

By "libraries" they mean the C source files in:

[SeeCwriter]

The documentation says that case sensitivity is not tested with example programs, drivers, and headers. I believe headers are compiled into your code.

I saw on the CCS download page a download for TCP/IP. I downloaded it and read the readme file, and it says that it's a port of the Microchip TCP/IP package for the version 3 CCS compiler. It also says that when version 4 of the CCS compiler is released (I guess this port is quite old) that the Microchip TCP/IP package will be able to be used almost "as is" with it since version 4 will have a linker and compatible pointers. Has anyone tried to use Microchip's TCP/IP package with version 4 of the CCS compiler?

I just looked at 18F452.H and almost everything in it is a constant, and
they are all in upper case, which is the C standard.
There are few #define statements which provide aliases for functions,
but they're all in lower case, which is also the C standard.
These two lines could conceivably be a problem, but these are the only ones:

I downloaded it. I did a text search, and Darren does use #case in
these files. I did a further search for "stacktsk.h", and it looks like
almost every file in TCP-IP directory #includes it. So that means
#case is likely used everywhere in that code.
