Not to my knowledge. Using an indented #error is a trick to get K&R C
compilers to accept #error. Without the indentation, a K&R C compiler
will be baffled by an unrecognized preprocessor directive (but will
fail if it tries to compile #error, giving the desired error, though
not the exact desired error message). The indented #error will be
recognized by an ISO C compiler.
If you don't care about K&R C compilers, then you can do either.
