GCC's GNAT front-end for Ada does such checks (search for "GNAT.Spelling_Checker").
The source code (at least versions I've found on the Web) does not refer to a
specific algorithm.


A few examples of detection:


hac-parser-expressions.adb:129:35: "Symst" is undefined
hac-parser-expressions.adb:129:35: possible misspelling of "Symset"


hac-parser-expressions.adb:129:35: "Sym_set" is undefined
hac-parser-expressions.adb:129:35: possible misspelling of "Symset"


hac-parser-expressions.adb:129:35: "Sysmet" is undefined
hac-parser-expressions.adb:129:35: possible misspelling of "Symset"
