php-src/ext/sybase/sybase.c
Stig Bakken 2c0ad3ee25 last bunch of extensions moving to ext/ 
fhttpd module taken out of functions, functions is ready to go.
The only extensions I have tested are gd+freetype and odbc(solid).
Please try compiling in your favourite extensions and let me know how it
works.
