In a word, no.  (Well, not unless you commit vile acts with the obscure
token-concatenation operator, and set up your program to perform said vile
acts on every such identifier.)

You want a general text-manipulation tool like sed, not the C preprocessor.
Try "sed 's/Mta/Sendmail/g' file.proto >file.c".
