Kwiminyaka emine emva kohlaziyo lokugqibela, i-GNU M4 macro processor 1.4.20 yakhululwa, esetyenziswa njengesonga sokwenza uqwalaselo lwe-sendmail kunye nokuvelisa izikripthi zoqwalaselo kwi-Autoconf toolkit. I-M4 ikuvumela ukuba uvelise ngokutshintshatshintshayo okubhaliweyo okusekwe kwitemplates, ugqitha kumbhalo wegalelo kwaye uguqule isiphumo sokuphumeza iimakhro ezichazwe kulo mbhalo. IiMacros zinokubiza zombini imisebenzi yasekhaya kunye nesele ilungile, umzekelo, ukubandakanya iifayile, ukwenza imisebenzi ye-arithmetic, ukuguqula idatha yomtya, kwaye usebenzise imiyalelo yenkqubo.
Kwinguqulelo entsha:
- Ukuphunyezwa kweengxelo "eval" kuye kwakhawuleziswa ngokubonakalayo.
- Ukuhambelana nemigangatho emitsha yolwimi lwe-C kuye kwaqinisekiswa.
- Izilungiso ezifakwe kwi-gnulib ukulungisa imiba yokuphatheka.
- Imiyalelo ethi "syscmd" kunye ne "esyscmd" ngoku ibamba amabinzana elayini yomyalelo aqala ngeesimboli "+" kunye "-".
- Kwenziwa kusebenze okuchanekileyo kwendlela yokubini xa kulayishwa iifayile eziphathekayo kumaqonga angeyo-Unix, apho iifayile zokubini zicutshungulwa ngokwahlukileyo kuneefayile ezibhaliweyo (umzekelo, iimpawu ekupheleni komgca zitshintshwa).
