Revision cd4c4e2481dd6fcb7ceb39242fa722993f8c0ab1 authored by Ben Walton on 05 February 2012, 22:32:21 UTC, committed by Junio C Hamano on 06 February 2012, 00:32:33 UTC
As both of these compatibility wrappers include git-compat-utils.h, all of the system includes were redundant. Dropping these system includes also makes git-compat-utils.h the first include which avoids a compiler warning on Solaris due to the redefinition of _FILE_OFFSET_BITS.
