You've all the sympathy I can muster.

Functions defined in the class (the DO SOMTHING in the class) are inline by
default, IIRC, though I may be wrong about this. This is opposed to
functions that merely are DECLARED in the class, with the definition
elsewhere. Usually with classes, you make two files.
1: myclass.h --everything you need to know to use the class
2:myclass.c --the gory details of the implementation
gcc is warning you that it expects something fast and small, but instead
found looping constructions, that can be arbitrarily large, so aren't
elegible for "inlining." It shouldn't affect operation, assuming that
everything else is correct.

graphics.lib isn't part of djgpp. You want Allegro, but you need to learn
quite a bit more before you can use it.
If you read Stroustrup, and I encourage you to, you will find a reasonable
definition of OOP--decide what data you need to look at, and create methods
that do this.
A better structure for Dorit would be to have a constructor that takes a
string (you have no constructor) and assigns it to "line", or perhaps an
assignment operator (=) that assigns dorit::line from a string.
Then the method dorit::thinking can take the character to search for as
input.
The resulting main() looks like this:
main()
{
Dorit blushing;
char Mystring[80], lookfor;
cin >> Mystring;
blushing = Mystring; // call the assignment operator for dorit
// Get the char to search for
blushing.thinking(lookfor);
}
Good luck
