# Project: gvimext
# Generates gvimext.dll with gcc.
# Can be used for Cygwin and MingW (MingW ignores -mno-cygwin)
#
# Originally, the DLL base address was fixed: -Wl,--image-base=0x1C000000
# Now it is allocated dymanically by the linker by evaluating all DLLs
# already loaded in memory. The binary image contains as well information
# for automatic pseudo-rebasing, if needed by the system. ALV 2004-02-29

# If cross-compiling set this to yes, else set it to no
CROSS = no
#CROSS = yes
# For the old MinGW 2.95 (the one you get e.g. with debian woody)
# set the following variable to yes and check if the executables are
# really named that way.
# If you have a newer MinGW or you are using cygwin set it to no and
# check also the executables
MINGWOLD = no
