RE: if-conditionals

[Alexander.Farber]

Thanks, actually my biggest problem is matching 
a text string in a case-insensitive way: 

        ifeq (KSRT, $(findstring KSRT, $(TARGET)))

Do I have to come up here with something ugly like:

        $(shell echo $(TARGET) | tr 'A-z' 'a-z')

Also, I'm not sure what are the user-defined 
functions everyone keeps talking about on this list. 
We use gmake 3.81 (+some patch) on Linux/HP-UX here.

And for the spaces after commas - the whitespace after
the commas seems to be stripped or am I wrong here:

bolinux72:make-test {86} cat Makefile2
CC=gcc
ifeq ($(CC), gcc)
$(warning OK)
endif

all:

bolinux72:make-test {87} gmake -f Makefile2
Makefile2:3: OK
gmake: Nothing to be done for `all'.


Regards
Alex
