After searching my game base, I located 190 out of 6,168,985 games, with the pawns at: wPa4, b3, c4, d3, e4, f3, g4, h3.
I discarded those games that one or both of the opponents lacked a rating, leaving 113 games. I found by tabulating the results (1-0, 1/2 or 0-1) against the rating of the players (between 1900 to 2200), that the score was 27% in 77 games (5+ 31= 41-) .
The most frequent openings were:
English: symmetrical variation 20
Nimzovich-Larsen attack 30
Sicilian 13
Others 50
Total 113
With the statistics we can conclude that White's pawn configuration does not favor him.
