Both the options will compile all the PL/SQL in the resultant .FMX, .PLX, or .MMX file but COMPILE_ALL=YES also changes the cached version in the source .FMB, .PLL, or .MMB file. This confuses version control and build tools (CVS, Subversion, make, scons); they believe you’ve made significant changes to the source. COMPILE_ALL=SPECIAL does not do this.
