php-src/ext/standard/microtime.c
Stig Bakken 117a2fba07 * fixed some #if/#ifdef issues
* hand-patched in php3 changes from 3.0.6 to HEAD in these files:
   fopen-wrappers.[ch] ext/standard/file.[ch] ext/standard/fsock.[ch]
   ext/standard/php3_string.h ext/standard/string.c
* added some new file/socket macros for more readable code:
   FP_FGETS(buf,len,sock,fp,issock)
   FP_FREAD(buf,len,sock,fp,issock)
   FP_FEOF(sock,fp,issock)
   FP_FGETC(sock,fp,issock)
