Problem with comments in macros

[Shambler]

Just noting a small (and hard to track) issue I had with precompiler macros; unless you're making heavy/advanced use of macros, you probably wont come across this issue.

If you encapsulate multiple lines of code in a macro, including comments, it will not compile if any of the comments contain the character `, because the precompiler will incorrectly try to parse a macro within the comment.

Example (this does not compile):

`define TESTMACRO(A) `A

function Blah()
{
     `TESTMACRO(// The macro `WEWT does not exist)
}

(this compiles):

`define TESTMACRO(A) `A

function Blah()
{
     `TESTMACRO(// The macro WEWT does not exist)
}

The only difference between the two, is a ` within the commented text.


The code I was originally working with, which caused this issue (deliberately missing a lot of context, as the only relevant line is the comment):

`SET_PROPACCESS(GetObjAddress(SourceObj) + SourcePropertyObj.Offset, OrigAccessAddress,
	`SET_UPROP_OFFSET(default.PropArrayRef, 0, OrigPropOffset,
		SourceSize = default.PropAccess.ArrayRef.ArrayNum;
	)

	// Skips using `SET_PROPACCESS as it should not be used recursively
	default.DefaultObj.PropAccessAddress = GetObjAddress(DestObj) + DestPropertyObj.Offset;

	`SET_UPROP_OFFSET(default.PropArrayRef, 0, OrigPropOffset,
		DestSize = default.PropAccess.ArrayRef.ArrayNum;
	)
)

Thanks for the report. We see the same thing here and we'll get it fixed as quickly as priorities allow.

Also worth noting is that the , character causes the same problem, and possibly others too, so worth testing a wide range of unusual characters.
