# Build cryptlib, taking into account OS-specific quirks.  We have to 
# special-case the situation where the OS name is an alias for uname rather 
# than being predefined (this occurs when cross-compiling), because the 
# resulting expansion would contain two levels of `` escapes.  To handle 
# this, we leave a predefined OS name in place, but replace a call to uname 
# with instructions to the osversion.sh script to figure it out for itself.  
# In addition since $CROSSCOMPILE is usually a null value, we add an extra 
# character to the comparison string to avoid syntax errors.  Finally, we
# put the CFLAGS on a single line to avoid visual problems through adding a
# line break and long string of whitespace in the middle of the definition.
