The position is dead-equal, according to the analysis engines Stockfish10 and Komodo10.
41.Kc3 Kc5 42.g4 g5?
42.f5 holds. The problem with the text is the white king will get access to the e4 square.
43.f5
This is probably good enough, but even stronger is 43.fxg5 fxg5 44.b4+! axb4+ 45.Kd3 Kd5 46.b3 h6 47.h3 when Black is in zugzwang. Note that if 42...f5 had been played, this idea does not work, eg 43.g5 Kd5 44.b4 axb4+ 45.Kd3 Kc5 - White's king cannot advance because the e4 square is covered. If in this line White plays 45.Kxb4 then 45...Ke4 leads to an equal queen-and-pawn ending.
43...Kb5 44.b4?
Winning seems to be 44.Kd4 Kb4 45.Kd5 Kxb3 46.Ke6 Kxb2 47.Kxf6 a4 48.Kxg5 - both players will queen but White will be a pawn up with what looks like sufficient shelter for his king as well as threats against Black's remaining pawn.
44...a4 45.Kd2 Kb4 46.h4!? h6
46...gxh4 also seems to draw.
47.hxg5 hxg5 48.Kc2
I offered a draw.
48...Kc4

49.Kd2?
White holds with 49.Kb1 as 49...Kd4 50.Ka2 Ke3 51.Ka3 Kf3 52.Kxa4 Kxg4 is a draw, according to the Nalimov endgame tablebase.
The game finished:
49...Kd4 50.Kc2 Ke4 51.Kc3 Kf4 52.Kb4 Kxg4 53.Kxa4 Kxf5 54.b4 g4 55.b5 g3 56.b6 g2 57.b7 g1=R 0-1
