    I was able to compile the code below by simply running 'gcc itoa.c'.
    No additional libs needed to be linked in. (Removing the leading
    underscores made no difference at all.)

    Will it build for you ? Your post suggests that it won't - but if you
    can get that code to compile, then you should not have that trouble with
    Win32::API.

    I am using Mingw (but not Cygwin). Doing a search of your compiler's
    '.a' files for the string 'itoa' should throw up something. I get
    matches in 7 separate files including libcrtdll.a, libmsvcrt.a and
    libntdll.a. Is 'itoa' not defined in *any* of your library files ? If
    it's simply not there, then I don't know what you can do - maybe the
    Cygwin list would be able to provide better help.

    #include <stdlib.h>
    #include <stdio.h>

    int main()
    {
        char buffer[20];
        int i = 3445;
        long l = -344115L;
        unsigned long ul = 1234567890UL;

        _itoa( i, buffer, 10 );
        printf( "String of integer %d (radix 10): %s\n", i, buffer );
        _itoa( i, buffer, 16 );
        printf( "String of integer %d (radix 16): 0x%s\n", i, buffer );
        _itoa( i, buffer, 2 );
        printf( "String of integer %d (radix 2): %s\n", i, buffer );

        _ltoa( l, buffer, 16 );
        printf( "String of long int %ld (radix 16): 0x%s\n", l,
                                                         buffer );

        _ultoa( ul, buffer, 16 );
        printf( "String of unsigned long %lu (radix 16): 0x%s\n", ul,
                                                         buffer );
    }

    Hth .... somehow :-)

    Cheers,
