I am getting whole lot of Compiler Errors when i try to compile c and h
files compiled under cygwin.
I have to ( i must) port this c files and header files to vc++ 6.0 in order
to develop my program.
These are libIAX2.0 libraries.
i believe its a problem with the compiler.
I can t figure out what setting(s) i need to change in order for these
errors to disapper.
:)
