ASM code license question

Apr 28, 2010 at 7:14 PM

I'm planning to use EasyHooks in a commercial product and while digging through the code I came across the following comments:

; This code was generated by IDA Pro 5.0, by disassembling the machine
; code of the x86 ILD engine. Of course I had to apply some tricky workarounds
; to get a label-based jump table instead of an value-base one, which would
; make the file uneditable... I also had to rewrite many sections to be
; compatible with 64-Bit processors.

It looks like this code is actively used - can anybody give more details about the origin and license of the binaries that were reverse engineered to generate it and has any of the commercial products using easyhook (like EA) seen this as a potential problem ?
