# default build config for Linux
#LIBS?=   -ldl -lpthread
#CFLAGS?= -DNO_SSL

# Possible CFLAGS: (in brackets are rough numbers for 'gcc -O2' on i386)
# -DHAVE_MD5	- use system md5 library (-2kb)
# -DNDEBUG		- strip off all debug code (-5kb)
# -D_DEBUG		- build debug version (very noisy) (+6kb)
# -DNO_CGI		- disable CGI support (-5kb)
# -DNO_SSL		- disable SSL functionality (-2kb)
# -DNO_AUTH		- disable authorization support (-4kb)
# -DCONFIG=\"file\"	- use `file' as the default config file
# -DNO_SSI		- disable SSI support (-4kb)
# -DNO_THREADS	- disable threads support (?)

# XXX Note for the windows users. In order to build shttpd, MSVS6 is needed.
# Follow these steps:
# 1. Add c:\path_to_msvs6\bin to the system Path environment variable.
# 2. Add two new system environment variables:
#    LIB=c:\path_to_msvs6\lib
#    INCLUDE=c:\path_to_msvs6\include
# 3. start console, go to shttpd-VERSION\src\ directory
# 4. type "nmake msvc"
# 5. go to shttpd-VERSION\examples , type "nmake msvc"
