Hi Daniel,
signal.h is not a library. It is just an include files that contains some macro
definitions.
#define eint() __asm__ __volatile__("eint"::)
which just puts an assembly command into the code flow.
Also the interrupt functions are just defines that allow you to write
interrupt (vector) name (void)
instead of
void __attribute__((interrupt (vector))) name (void)
If you write the long forms yourself in your coude, you can do easily without
signal.h.
But why should you? It does not add any code by itself. It just makes your code
more readable and saves you some keystrokes.
But your error messages indicate that you didn't include it in this particular
code file. Therefore you cannot use its 'shortcuts' such as dint() in this code
file without an error.

#include <signal.h> exists in all the files that need it, I thought that
this library is not found because in mspgcc manual by Steve says that is
necessary not only for dint/eint but also to process interrups
functions, which is the case.
