3.0.14 Thanks for the feedback.

That could make sense the errors I corrected to compile were pretty "grave".

For example compiling apc_cache.c I was getting the error:
C:\php521\ext\apc\apc_compile.c(1269) : error C2065: 'len' : undeclared identifier

So a looked at the 3.0.12 version and saw the $len was defined and added:
int len;
len = strlen(src->filename);

The 2 other errors were the same in different files:
C:\php521\ext\apc\apc_sma.c(59) : error C2061: syntax error : identifier 'apc_lck_t'
Added:
#define apc_lck_t int
just before the error.

Could someone else could confirm problems with 3.0.14 or not.

Thanks,
Chris
