## Makefile for building libcurl.a with MingW (GCC-3.2 or later)
## and optionally OpenSSL (1.0.2a), libssh2 (1.5), zlib (1.2.8), librtmp (2.4)
##
## Usage:   mingw32-make -f Makefile.m32 CFG=-feature1[-feature2][-feature3][...]
## Example: mingw32-make -f Makefile.m32 CFG=-zlib-ssl-sspi-winidn
##
## Hint: you can also set environment vars to control the build, f.e.:
## set ZLIB_PATH=c:/zlib-1.2.8
## set ZLIB=1
#
