    Free Windows C Compile that give good warning?

    I am working on an embedded project that uses a C-like compiler (Rabbit Dynamic C 9.6) and I wish to speed up the Edit/Build/Test Cycle.

    I have decided to use an Windows C Compiler to test my code for valid syntax and operation in some cases.

    I am looking for C Compiler that give good warnings for non standard code.

    I am currently testing MinGW GCC, Watcom, and LLVM C compliers.
    I plan to add Pelles C Compiler to my list of test Compilers.

    Is there any other C Compilers that I should consider?

    I have tried SDCC and Digital Mars C compilers and decided they would require to much work to get the project code to successfully compile.

    If you go into the project settings in PellesC and set the warnings level to high, it will drive you positively crazy with all the stuff it tells you about. It is very comprehensive.

    Also, you should give some thought to how much time you could waste getting it working on C when you have to ultimately get it working on RD... They are very alike, but not the same. Is there no way to produce a higher level of warning in the code's final compiler?

    I have been using MinGW GCC for about a year to generate Compiler Warnings; it has taken me the past 2 days to get it to link using MinGW.

    The main warning, that decided me to use MinGW GCC was printf string format checking for right variable type.
    I wasted 4 hours because I did not see a printf problem; so I spent my free time for several days getting the code to compile using MinGW GCC.

    Rabbit DC 9 does not really give good warnings; and I hope to port to a real C Compiler in the future.
    A example of how much it is NOT a C Compiler, Rabbit DC 9 does NOT support "#include".

    Rabbit DC 10 does support "#include", so I hope to port some of the source code to it or a real C Compiler in the future.

    Using an Windows C Compiler, I hope to save about 3 to 5 minutes time downloading the binary into the MCU. Part of the project uses an serial LCD display, I hope to save a lot of time spent doing minor adjustment of the appearance of LCD display.

    I also wish to do unit tests of several functions on a PC platform.
