Ja, det kan tyckas lite märkligt. Men med tanke på åldern på
språket kan man väl ta det, moderna språk slipper helt headerfilerna

Självklart. Ska sluta gnälla och plocka fram "rätt" saker istället.
Här är alltså länken. Den snackar visserligen om en gammal hi-tech,
men XC8 är ju hi-techs kompilator. xc.h inkluderar bara htc.h vilken
var den filen man skulle inkludera med hi-techs version.

Där ser du de tre varningarna där han gör om mina funktionsanrop
till funktionsdeklarationer.

Filerna lägger jag till genom att högerklicka på mappen "source files"
och väljer "C source file" samt "header files" och väljer "c header file"
EDIT:
Kan tillägga att mapparna "header files" och "source files" inte finns i
verkligheten utan verkar vara nått som MPLAB X har fantiserat ihop.
Men eftersom interrupt.c och interrupt.h ligger i dessa och fungerar
bra (nu) så borde det vara så det ska vara.
