2006-01-07[PATCH] Compilation: zero-length array declaration.Junio C Hamano
ISO C99 (and GCC 3.x or later) lets you write a flexible array at the end of a structure, like this: struct frotz { int xyzzy; char nitfol[]; /* more */ }; GCC 2.95 and 2.96 let you to do this with "char nitfol[0]"; unfortunately this is not allowed by ISO C90. This declares such construct like this: struct frotz { int xyzzy; char nitfol[FLEX_ARRAY]; /* more */ }; and git-compat-util.h defines FLEX_ARRAY to 0 for gcc 2.95 and empty for others. If you are using a C90 C compiler, you should be able to override this with CFLAGS=-DFLEX_ARRAY=1 from the command line of "make". Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-12-20xread/xwrite: do not worry about EINTR at calling sites.Junio C Hamano
We had errno==EINTR check after read(2)/write(2) sprinkled all over the places, always doing continue. Consolidate them into xread()/xwrite() wrapper routines. Credits for suggestion goes to HPA -- bugs are mine. Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-12-05Clean up compatibility definitions.Junio C Hamano
This attempts to clean up the way various compatibility functions are defined and used. - A new header file, git-compat-util.h, is introduced. This looks at various NO_XXX and does necessary function name replacements, equivalent of -Dstrcasestr=gitstrcasestr in the Makefile. - Those function name replacements are removed from the Makefile. - Common features such as usage(), die(), xmalloc() are moved from cache.h to git-compat-util.h; cache.h includes git-compat-util.h itself.
